# CompactDecimalFormat Added in[API level 24](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) # CompactDecimalFormat *** ** * ** *** Kotlin\|[Java](https://developer.android.com/reference/android/icu/text/CompactDecimalFormat "View this page in Java") ``` open class CompactDecimalFormat : DecimalFormat ``` |---|---|---|---|---|--------------------------------------------------------------------------------------------------------------------------------| | [kotlin.Any](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-any/index.html) |||||| | ↳ | [java.text.Format](https://developer.android.com/reference/kotlin/java/text/Format.html#) ||||| | | ↳ | [android.icu.text.UFormat](https://developer.android.com/reference/kotlin/android/icu/text/UFormat) |||| | | | ↳ | [android.icu.text.NumberFormat](https://developer.android.com/reference/kotlin/android/icu/text/NumberFormat) ||| | | | | ↳ | [android.icu.text.DecimalFormat](https://developer.android.com/reference/kotlin/android/icu/text/DecimalFormat) || | | | | | ↳ | [android.icu.text.CompactDecimalFormat](https://developer.android.com/reference/kotlin/android/icu/text/CompactDecimalFormat#) | Formats numbers in compact (abbreviated) notation, like "1.2K" instead of "1200". **IMPORTANT:** New users are strongly encouraged to see if[NumberFormatter](https://developer.android.com/reference/kotlin/android/icu/number/NumberFormatter.html#)fits their use case. Although not deprecated, this class, CompactDecimalFormat, is provided for backwards compatibility only. The CompactDecimalFormat produces abbreviated numbers, suitable for display in environments will limited real estate. For example, 'Hits: 1.2B' instead of 'Hits: 1,200,000,000'. The format will be appropriate for the given language, such as "1,2 Mrd." for German. For numbers under 1000 trillion (under 10\^15, such as 123,456,789,012,345), the result will be short for supported languages. However, the result may sometimes exceed 7 characters, such as when there are combining marks or thin characters. In such cases, the visual width in fonts should still be short. By default, there are 2 significant digits. After creation, if more than three significant digits are set (with setMaximumSignificantDigits), or if a fixed number of digits are set (with setMaximumIntegerDigits or setMaximumFractionDigits), then result may be wider. The "short" style is also capable of formatting currency amounts, such as "$1.2M" instead of "$1,200,000.00" (English) or "5,3 Mio. €" instead of "5.300.000,00 €" (German). Localized data concerning longer formats is not available yet in the Unicode CLDR. Because of this, attempting to format a currency amount using the "long" style will produce an UnsupportedOperationException. At this time, negative numbers and parsing are not supported, and will produce an UnsupportedOperationException. Resetting the pattern prefixes or suffixes is not supported; the method calls are ignored. Note that important methods, like setting the number of decimals, will be moved up from DecimalFormat to NumberFormat. ## Summary | Nested classes || |---|-------------------------------------------------------------------------------------------------------------------------------------------------------------| | | [CompactStyle](https://developer.android.com/reference/kotlin/android/icu/text/CompactDecimalFormat.CompactStyle) Style parameter for CompactDecimalFormat. | | Inherited constants || |---|---| | From class[NumberFormat](https://developer.android.com/reference/kotlin/android/icu/text/NumberFormat) |----------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | [Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html) | [ACCOUNTINGCURRENCYSTYLE](https://developer.android.com/reference/kotlin/android/icu/text/NumberFormat#ACCOUNTINGCURRENCYSTYLE:kotlin.Int)

Converts the given string to standard notation and then parses it using[applyPattern](https://developer.android.com/reference/kotlin/android/icu/text/DecimalFormat#applyPattern(kotlin.String)). This method is provided for backwards compatibility and should not be used in new projects. Localized notation means that instead of using generic placeholders in the pattern, you use the corresponding locale-specific characters instead. For example, in locale*fr-FR*, the period in the pattern "0.000" means "decimal" in standard notation (as it does in every other locale), but it means "grouping" in localized notation.

Formats an Object producing an`AttributedCharacterIterator`. You can use the returned`AttributedCharacterIterator`to build the resulting String, as well as to determine information about the resulting String. Each attribute key of the AttributedCharacterIterator will be of type`Field`.

The default implementation creates an`AttributedCharacterIterator`with no attributes. Subclasses that support fields should override this and create an`AttributedCharacterIterator`with meaningful attributes.

| | [Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html) | [hashCode](https://developer.android.com/reference/kotlin/android/icu/text/DecimalFormat#hashCode())`()`
Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by[java.util.HashMap](https://developer.android.com/reference/kotlin/java/util/HashMap.html#). The general contract of`hashCode`is: - Whenever it is invoked on the same object more than once during an execution of a Java application, the`hashCode`method must consistently return the same integer, provided no information used in`equals`comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application. - If two objects are equal according to the[equals](https://developer.android.com/reference/kotlin/java/lang/Object.html#equals(kotlin.Any))method, then calling the`hashCode`method on each of the two objects must produce the same integer result. - It is*not* required that if two objects are unequal according to the[equals](https://developer.android.com/reference/kotlin/java/lang/Object.html#equals(kotlin.Any))method, then calling the`hashCode`method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

**\[icu\]**Returns whether to force case (uppercase/lowercase) to match when parsing.
| | [Boolean](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html) | [isParseIntegerOnly](https://developer.android.com/reference/kotlin/android/icu/text/DecimalFormat#isParseIntegerOnly())`()`
Returns true if this format will parse numbers as integers only. For example in the English locale, with ParseIntegerOnly true, the string "1234." would be parsed as the integer value 1234 and parsing would stop at the "." character. The decimal separator accepted by the parse operation is locale-dependent and determined by the subclass.
| | [Boolean](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html) | [isParseNoExponent](https://developer.android.com/reference/kotlin/android/icu/text/DecimalFormat#isParseNoExponent())`()`

Sets the currency to be used when formatting numbers. The effect is twofold: 1. Substitutions for currency symbols in the pattern string will use this currency 2. The rounding mode will obey the rules for this currency (see[setCurrencyUsage](https://developer.android.com/reference/kotlin/android/icu/text/DecimalFormat#setCurrencyUsage(android.icu.util.Currency.CurrencyUsage))) **Important:** Displaying the currency in the output requires that the patter associated with this formatter contains a currency symbol '¤'. This will be the case if the instance was created via #getCurrencyInstance or one of its friends.

**\[icu\]**Sets a custom instance of CurrencyPluralInfo. CurrencyPluralInfo generates pattern strings for printing currency long names. **Most users should not call this method directly.** You should instead create your formatter via`NumberFormat.getInstance(NumberFormat.PLURALCURRENCYSTYLE)`.
| | [Unit](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html) | [setCurrencyUsage](https://developer.android.com/reference/kotlin/android/icu/text/DecimalFormat#setCurrencyUsage(android.icu.util.Currency.CurrencyUsage))`(`usage:` `[Currency.CurrencyUsage](https://developer.android.com/reference/kotlin/android/icu/util/Currency.CurrencyUsage.html#)!`)`
**\[icu\]**Sets the currency-dependent strategy to use when rounding numbers. There are two strategies: - STANDARD: When the amount displayed is intended for banking statements or electronic transfer. - CASH: When the amount displayed is intended to be representable in physical currency, like at a cash register. CASH mode is relevant in currencies that do not have tender down to the penny. For more information on the two rounding strategies, see[UTS #35](http://unicode.org/reports/tr35/tr35-numbers.html#Supplemental_Currency_Data). If omitted, the strategy defaults to STANDARD. To override currency rounding altogether, use[setMinimumFractionDigits](https://developer.android.com/reference/kotlin/android/icu/text/DecimalFormat#setMinimumFractionDigits(kotlin.Int))and[setMaximumFractionDigits](https://developer.android.com/reference/kotlin/android/icu/text/DecimalFormat#setMaximumFractionDigits(kotlin.Int))or #setRoundingIncrement.

Sets the decimal format symbols used by this formatter. The formatter uses a copy of the provided symbols.
| | [Unit](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html) | [setDecimalPatternMatchRequired](https://developer.android.com/reference/kotlin/android/icu/text/DecimalFormat#setDecimalPatternMatchRequired(kotlin.Boolean))`(`value:` `[Boolean](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html)`)`
**\[icu\]** **Parsing:** This method is used to either*require*or the presence of a decimal point in the string being parsed (disabled by default). This feature was designed to be an extra layer of strictness on top of strict parsing, although it can be used in either lenient mode or strict mode. To*require* a decimal point, call this method in combination with either a pattern containing a decimal point or with[setDecimalSeparatorAlwaysShown](https://developer.android.com/reference/kotlin/android/icu/text/DecimalFormat#setDecimalSeparatorAlwaysShown(kotlin.Boolean)). ```kotlin // Require a decimal point in the string being parsed: df.applyPattern("#."); df.setDecimalPatternMatchRequired(true); // Alternatively: df.setDecimalSeparatorAlwaysShown(true); df.setDecimalPatternMatchRequired(true); ``` To*forbid* a decimal point, call this method in combination with a pattern containing no decimal point. Alternatively, use[setParseIntegerOnly](https://developer.android.com/reference/kotlin/android/icu/text/DecimalFormat#setParseIntegerOnly(kotlin.Boolean))for the same behavior without depending on the contents of the pattern string. ```kotlin // Forbid a decimal point in the string being parsed: df.applyPattern("#"); df.setDecimalPatternMatchRequired(true); ```
| | [Unit](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html) | [setDecimalSeparatorAlwaysShown](https://developer.android.com/reference/kotlin/android/icu/text/DecimalFormat#setDecimalSeparatorAlwaysShown(kotlin.Boolean))`(`value:` `[Boolean](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html)`)`
**Separators:** Sets whether the decimal separator (a period in*en-US*) is shown on integers. For example, if this setting is turned on, formatting 123 will result in "123." with the decimal separator. This setting can be specified in the pattern for integer formats: "#,##0." is an example.
| | [Unit](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html) | [setExponentSignAlwaysShown](https://developer.android.com/reference/kotlin/android/icu/text/DecimalFormat#setExponentSignAlwaysShown(kotlin.Boolean))`(`expSignAlways:` `[Boolean](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html)`)`
**\[icu\]** **Scientific Notation:** Sets whether the sign (plus or minus) is always to be shown in the exponent in scientific notation. For example, if this setting is enabled, the number 123000 will be printed as "1.23E+5" in locale*en-US* . The number 0.0000123 will always be printed as "1.23E-5" in locale*en-US*whether or not this setting is enabled. This setting corresponds to the '+' in a pattern such as "0.00E+0".
| | [Unit](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html) | [setFormatWidth](https://developer.android.com/reference/kotlin/android/icu/text/DecimalFormat#setFormatWidth(kotlin.Int))`(`width:` `[Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html)`)`
**Padding:**Sets the minimum width of the string output by the formatting pipeline. For example, if padding is enabled and paddingWidth is set to 6, formatting the number "3.14159" with the pattern "0.00" will result in "··3.14" if '·' is your padding string. If the number is longer than your padding width, the number will display as if no padding width had been specified, which may result in strings longer than the padding width. Padding can be specified in the pattern string using the '\*' symbol. For example, the format "\*x######0" has a format width of 7 and a pad character of 'x'. Padding is currently counted in UTF-16 code units; see[ticket #13034](https://unicode-org.atlassian.net/browse/ICU-13034)for more information.

**Grouping:**Sets the primary grouping size (distance between grouping separators) used when formatting large numbers. For most locales, this defaults to 3: the number of digits between the ones and thousands place, between thousands and millions, and so forth. For example, with a grouping size of 3, the number 1234567 will be formatted as "1,234,567". Grouping size can also be specified in the pattern: for example, "#,##0" corresponds to a grouping size of 3.
| | [Unit](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html) | [setGroupingUsed](https://developer.android.com/reference/kotlin/android/icu/text/DecimalFormat#setGroupingUsed(kotlin.Boolean))`(`enabled:` `[Boolean](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html)`)`
**Grouping:** Sets whether grouping is to be used when formatting numbers. Grouping means whether the thousands, millions, billions, and larger powers of ten should be separated by a grouping separator (a comma in*en-US*). For example, if grouping is enabled, 12345 will be printed as "12,345" in*en-US*. If grouping were disabled, it would instead be printed as simply "12345".

**\[icu\]** **Rounding and Digit Limits:** Sets the[java.math.MathContext](https://developer.android.com/reference/kotlin/java/math/MathContext.html#)used to round numbers. A "math context" encodes both a rounding mode and a number of significant digits. Most users should call[setRoundingMode](https://developer.android.com/reference/kotlin/android/icu/text/DecimalFormat#setRoundingMode(kotlin.Int))and/or[setMaximumSignificantDigits](https://developer.android.com/reference/kotlin/android/icu/text/DecimalFormat#setMaximumSignificantDigits(kotlin.Int))instead of this method. When formatting, since no division is ever performed, the default MathContext is unlimited significant digits. However, when division occurs during parsing to correct for percentages and multipliers, a MathContext of 34 digits, the IEEE 754R Decimal128 standard, is used by default. If you require more than 34 digits when parsing, you can set a custom MathContext using this method.
| | [Unit](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html) | [setMathContextICU](https://developer.android.com/reference/kotlin/android/icu/text/DecimalFormat#setMathContextICU(android.icu.math.MathContext))`(`mathContextICU:` `[MathContext](https://developer.android.com/reference/kotlin/android/icu/math/MathContext.html#)!`)`
**\[icu\]** **Rounding and Digit Limits:** Overload of[setMathContext](https://developer.android.com/reference/kotlin/android/icu/text/DecimalFormat#setMathContext(java.math.MathContext))for[android.icu.math.MathContext](https://developer.android.com/reference/kotlin/android/icu/math/MathContext.html#).

**Rounding and Digit Limits:**Sets the maximum number of digits to display after the decimal separator. If the number has more than this many digits, the number is rounded according to the rounding mode. For example, if maximum fraction digits is 2, the number 123.456 will be printed as "123.46". Minimum integer and minimum and maximum fraction digits can be specified via the pattern string. For example, "#,#00.00#" has 2 minimum integer digits, 2 minimum fraction digits, and 3 maximum fraction digits. Note that it is not possible to specify maximum integer digits in the pattern except in scientific notation. If minimum and maximum integer, fraction, or significant digits conflict with each other, the most recently specified value is used. For example, if there is a formatter with minInt=5, and then you set maxInt=3, then minInt will be changed to 3.

**Rounding and Digit Limits:**Sets the maximum number of digits to display before the decimal separator. If the number has more than this many digits, the number is truncated. For example, if maximum integer digits is 3, the number 12345 will be printed as "345". Minimum integer and minimum and maximum fraction digits can be specified via the pattern string. For example, "#,#00.00#" has 2 minimum integer digits, 2 minimum fraction digits, and 3 maximum fraction digits. Note that it is not possible to specify maximum integer digits in the pattern except in scientific notation. If minimum and maximum integer, fraction, or significant digits conflict with each other, the most recently specified value is used.

**\[icu\]** **Rounding and Digit Limits:**Sets the maximum number of significant digits to be displayed. If the number of significant digits in the number exceeds this value, the number will be rounded according to the current rounding mode. For example, if maximum significant digits is 3 and the number is 12345, the number will be printed as "12300". If minimum and maximum integer, fraction, or significant digits conflict with each other, the most recently specified value is used. For example, if there is a formatter with minInt=5, and then you set maxInt=3, then minInt will be changed to 3. See #setRoundingIncrement and[setMaximumFractionDigits](https://developer.android.com/reference/kotlin/android/icu/text/DecimalFormat#setMaximumFractionDigits(kotlin.Int))for two other ways of specifying rounding strategies.

**\[icu\]** **Scientific Notation:**Sets the minimum number of digits to be printed in the exponent. For example, if minimum exponent digits is 3, the number 123000 will be printed as "1.23E005". This setting corresponds to the number of zeros after the 'E' in a pattern string such as "0.00E000".
| | [Unit](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html) | [setMinimumFractionDigits](https://developer.android.com/reference/kotlin/android/icu/text/DecimalFormat#setMinimumFractionDigits(kotlin.Int))`(`value:` `[Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html)`)`
**Rounding and Digit Limits:**Sets the minimum number of digits to display after the decimal separator. If the number has fewer than this many digits, the number is padded with zeros. For example, if minimum fraction digits is 2, the number 123.4 will be printed as "123.40". Minimum integer and minimum and maximum fraction digits can be specified via the pattern string. For example, "#,#00.00#" has 2 minimum integer digits, 2 minimum fraction digits, and 3 maximum fraction digits. Note that it is not possible to specify maximum integer digits in the pattern except in scientific notation. If minimum and maximum integer, fraction, or significant digits conflict with each other, the most recently specified value is used.

**\[icu\]** Sets the minimum number of digits that must be before the first grouping separator in order for the grouping separator to be printed. For example, if minimum grouping digits is set to 2, in*en-US*, 1234 will be printed as "1234" and 12345 will be printed as "12,345". Set the value to: - 1 to turn off minimum grouping digits. - MINIMUM_GROUPING_DIGITS_AUTO to display grouping using the default strategy for all locales. - MINIMUM_GROUPING_DIGITS_MIN2 to display grouping using locale defaults, except do not show grouping on values smaller than 10000 (such that there is a minimum of two digits before the first separator).

**\[icu\]** **Rounding and Digit Limits:**Sets the minimum number of significant digits to be displayed. If the number of significant digits is less than this value, the number will be padded with zeros as necessary. For example, if minimum significant digits is 3 and the number is 1.2, the number will be printed as "1.20".

Sets a number that will be used to multiply all numbers prior to formatting. For example, when formatting percents, a multiplier of 100 can be used. If a percent or permille sign is specified in the pattern, the multiplier is automatically set to 100 or 1000, respectively. If the number specified here is a power of 10, a more efficient code path will be used.

**Affixes:** Sets the string to prepend to negative numbers. For example, if you set the value "#", then the number -123 will be formatted as "#123" in the locale*en-US*(overriding the implicit default '-' in the pattern). Using this method overrides the affix specified via the pattern, and unlike the pattern, the string given to this method will be interpreted literally WITHOUT locale symbol substitutions.

**Parsing:**Sets whether to ignore the fraction part of a number when parsing (defaults to false). If a string contains a decimal point, parsing will stop before the decimal point. Note that determining whether a character is a decimal point depends on the locale. For example, in*en-US*, parsing the string "123.45" will return the number 123 and parse position 3. This is functionally equivalent to calling[setDecimalPatternMatchRequired](https://developer.android.com/reference/kotlin/android/icu/text/DecimalFormat#setDecimalPatternMatchRequired(kotlin.Boolean))and a pattern without a decimal point.

| | [Unit](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html) | [setParseStrict](https://developer.android.com/reference/kotlin/android/icu/text/DecimalFormat#setParseStrict(kotlin.Boolean))`(`parseStrict:` `[Boolean](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html)`)`
**\[icu\]**Sets whether strict parsing is in effect. When this is true, the string is required to be a stronger match to the pattern than when lenient parsing is in effect. More specifically, the following conditions cause a parse failure relative to lenient mode (examples use the pattern "#,##0.#"): - The presence and position of special symbols, including currency, must match the pattern. '+123' fails (there is no plus sign in the pattern) - Leading or doubled grouping separators ',123' and '1,,234" fail - Groups of incorrect length when grouping is used '1,23' and '1234,567' fail, but '1234' passes - Grouping separators used in numbers followed by exponents '1,234E5' fails, but '1234E5' and '1,234E' pass ('E' is not an exponent when not followed by a number) When strict parsing is off, all grouping separators are ignored. This is the default behavior.

**\[icu\]** **Rounding and Digit Limits:**Sets an increment, or interval, to which numbers are rounded. For example, a rounding increment of 0.05 will cause the number 1.23 to be rounded to 1.25 in the default rounding mode. The rounding increment can be specified via the pattern string: for example, the pattern "#,##0.05" encodes a rounding increment of 0.05. The rounding increment is applied*after* any multipliers might take effect; for example, in scientific notation or when[setMultiplier](https://developer.android.com/reference/kotlin/android/icu/text/DecimalFormat#setMultiplier(kotlin.Int))is used. See[setMaximumFractionDigits](https://developer.android.com/reference/kotlin/android/icu/text/DecimalFormat#setMaximumFractionDigits(kotlin.Int))and[setMaximumSignificantDigits](https://developer.android.com/reference/kotlin/android/icu/text/DecimalFormat#setMaximumSignificantDigits(kotlin.Int))for two other ways of specifying rounding strategies.

**Rounding and Digit Limits:** Sets the[RoundingMode](https://developer.android.com/reference/kotlin/java/math/RoundingMode.html#)used to round numbers. The default rounding mode is HALF_EVEN, which rounds decimals to their closest whole number, and rounds to the closest even number if at the midpoint. For more detail on rounding modes, see[the ICU User Guide](https://unicode-org.github.io/icu/userguide/format_parse/numbers/rounding-modes). For backwards compatibility, the rounding mode is specified as an int argument, which can be from either the constants in[BigDecimal](https://developer.android.com/reference/kotlin/android/icu/math/BigDecimal.html#)or the ordinal value of[RoundingMode](https://developer.android.com/reference/kotlin/java/math/RoundingMode.html#). The following two calls are functionally equivalent. ```kotlin df.setRoundingMode(BigDecimal.ROUND_CEILING); df.setRoundingMode(RoundingMode.CEILING.ordinal()); ```

**\[icu\]** **Scientific Notation:** Sets whether this formatter should print in scientific (exponential) notation. For example, if scientific notation is enabled, the number 123000 will be printed as "1.23E5" in locale*en-US*. A locale-specific symbol is used as the exponent separator. Calling`df.setScientificNotation(true)`is functionally equivalent to calling`df.setMinimumExponentDigits(1)`.

**\[icu\]** **Grouping:**Sets the secondary grouping size (distance between grouping separators after the first separator) used when formatting large numbers. In many south Asian locales, this is set to 2. For example, with primary grouping size 3 and secondary grouping size 2, the number 1234567 will be formatted as "12,34,567". Grouping size can also be specified in the pattern: for example, "#,##,##0" corresponds to a primary grouping size of 3 and a secondary grouping size of 2.
| | [Unit](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html) | [setSignAlwaysShown](https://developer.android.com/reference/kotlin/android/icu/text/DecimalFormat#setSignAlwaysShown(kotlin.Boolean))`(`value:` `[Boolean](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html)`)`
Sets whether to always shown the plus sign ('+' in*en*) on positive numbers. The rules in UTS #35 section 3.2.1 will be followed to ensure a locale-aware placement of the sign. More specifically, the following strategy will be used to place the plus sign: 1. *Patterns without a negative subpattern:*The locale's plus sign will be prepended to the positive prefix. 2. *Patterns with a negative subpattern without a '-' sign (e.g., accounting):*The locale's plus sign will be prepended to the positive prefix, as in case 1. 3. *Patterns with a negative subpattern that has a '-' sign:*The locale's plus sign will substitute the '-' in the negative subpattern. The positive subpattern will be unused. This method is designed to be used*instead of* applying a pattern containing an explicit plus sign, such as "+0;-0". The behavior when combining this method with explicit plus signs in the pattern is undefined.
