`NumberFormat` is the abstract base class for all number formats. This class provides the interface for formatting and parsing numbers. `NumberFormat` also provides methods for determining which locales have number formats, and what their names are. `NumberFormat` helps you to format and parse numbers for any locale. Your code can be completely independent of the locale conventions for decimal points, thousands-separators, or even the particular decimal digits used, or whether the number format is even decimal.
To format a number for the current Locale, use one of the factory
class methods:
>
> ```
> myString = NumberFormat.getInstance().format(myNumber);
> ```
If you are formatting multiple numbers, it is more efficient to get the format and use it multiple times so that the system doesn't have to fetch the information about the local language and country conventions multiple times.
>
> ```
> NumberFormat nf = NumberFormat.getInstance();
> for (int i = 0; i < a.length; ++i) {
> output.println(nf.format(myNumber[i]) + "; ");
> }
> ```
To format a number for a different Locale, specify it in the call to `getInstance`.
>
> ```
> NumberFormat nf = NumberFormat.getInstance(Locale.FRENCH);
> ```
You can also use a `NumberFormat` to parse numbers:
>
> ```
> myNumber = nf.parse(myString);
> ```
Use `getInstance` or `getNumberInstance` to get the normal number format. Use `getIntegerInstance` to get an integer number format. Use `getCurrencyInstance` to get the currency number format. And use `getPercentInstance` to get a format for displaying percentages. Some factory methods are found within subclasses of NumberFormat. With this format, a fraction like 0.53 is displayed as 53%.
Starting from ICU 4.2, you can use getInstance() by passing in a 'style'
as parameter to get the correct instance.
For example,
use getInstance(...NUMBERSTYLE) to get the normal number format,
getInstance(...PERCENTSTYLE) to get a format for displaying percentage,
getInstance(...SCIENTIFICSTYLE) to get a format for displaying scientific number,
getInstance(...INTEGERSTYLE) to get an integer number format,
getInstance(...CURRENCYSTYLE) to get the currency number format,
in which the currency is represented by its symbol, for example, "$3.00".
getInstance(...ISOCURRENCYSTYLE) to get the currency number format,
in which the currency is represented by its ISO code, for example "USD3.00".
getInstance(...PLURALCURRENCYSTYLE) to get the currency number format,
in which the currency is represented by its full name in plural format,
for example, "3.00 US dollars" or "1.00 US dollar".
You can also control the display of numbers with such methods as
`setMinimumFractionDigits`.
If you want even more control over the format or parsing,
or want to give your users more control,
you can try casting the `NumberFormat` you get from the factory methods
to a `DecimalFormat`. This will work for the vast majority
of locales; just remember to put it in a `try` block in case you
encounter an unusual one.
NumberFormat is designed such that some controls
work for formatting and others work for parsing. The following is
the detailed description for each these control methods,
setParseIntegerOnly : only affects parsing, e.g.
if true, "3456.78" -\> 3456 (and leaves the parse position just after '6')
if false, "3456.78" -\> 3456.78 (and leaves the parse position just after '8')
This is independent of formatting. If you want to not show a decimal point
where there might be no digits after the decimal point, use
setDecimalSeparatorAlwaysShown on DecimalFormat.
You can also use forms of the `parse` and `format`
methods with `ParsePosition` and `FieldPosition` to
allow you to:
- progressively parse through pieces of a string
- align the decimal point and other areas
For example, you can align numbers in two ways:
1. If you are using a monospaced font with spacing for alignment, you can pass the `FieldPosition` in your format call, with `field` = `INTEGER_FIELD`. On output, `getEndIndex` will be set to the offset between the last character of the integer and the decimal. Add (desiredSpaceCount - getEndIndex) spaces at the front of the string.
2. If you are using proportional fonts, instead of padding with spaces, measure the width of the string in pixels from the start to `getEndIndex`. Then move the pen by (desiredPixelWidth - widthToAlignmentPoint) before drawing the text. It also works where there is no decimal, but possibly additional characters at the end, e.g., with parentheses in negative numbers: "(12)" for -12.
### Synchronization
Number formats are generally not synchronized. It is recommended to create
separate format instances for each thread. If multiple threads access a format
concurrently, it must be synchronized externally.
#### DecimalFormat
DecimalFormat is the concrete implementation of NumberFormat, and the
NumberFormat API is essentially an abstraction from DecimalFormat's API.
Refer to DecimalFormat for more information about this API.

```
**NOTE:** New users are strongly encouraged to use
`https://developer.android.com/reference/android/icu/number/NumberFormatter` instead of NumberFormat.
*** ** * ** ***
Returns an integer number format for the specified locale. The returned number format is configured to round floating point numbers to the nearest integer using IEEE half-even rounding (see `https://developer.android.com/reference/android/icu/math/BigDecimal#ROUND_HALF_EVEN`) for formatting, and to parse only the integer part of an input string (see `https://developer.android.com/reference/android/icu/text/NumberFormat#isParseIntegerOnly()`).
| Parameters ||
|---|---|
| `inLocale` | `Locale`: the locale for which a number format is needed
|
| Returns ||
|---|---|
| `https://developer.android.com/reference/android/icu/text/NumberFormat` | a number format for integer values

### getMaximumFractionDigits
Added in [API level 24](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public int getMaximumFractionDigits ()
```
Returns the maximum number of digits allowed in the fraction
portion of a number. The default value is 3, which subclasses
can override. When formatting, the exact behavior when this
value is exceeded is subclass-specific. When parsing, this has
no effect.
| Returns ||
|---|---|
| `int` | the maximum number of fraction digits
|

```
public int getMaximumIntegerDigits ()
```
Returns the maximum number of digits allowed in the integer portion of a
number. The default value is 40, which subclasses can override.
When formatting, if the number of digits exceeds this value, the highest-
significance digits are truncated until the limit is reached, in accordance
with UTS#35.
This setting has no effect on parsing.
| Returns ||
|---|---|
| `int` | the maximum number of integer digits

### hashCode
Added in [API level 24](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public int hashCode ()
```
Returns a hash code value for the object. This method is
supported for the benefit of hash tables such as those provided by
`https://developer.android.com/reference/java/util/HashMap`.
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 `https://developer.android.com/reference/java/lang/Object#equals(java.lang.Object)` 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 `https://developer.android.com/reference/java/lang/Object#equals(java.lang.Object)` 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.
| Returns ||
|---|---|
| `int` | a hash code value for this object.
|
### isGroupingUsed
Added in [API level 24](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public boolean isGroupingUsed ()
```
Returns true if grouping is used in this format. For example, in the
en_US locale, with grouping on, the number 1234567 will be formatted
as "1,234,567". The grouping separator as well as the size of each group
is locale-dependent and is determined by subclasses of NumberFormat.
Grouping affects both parsing and formatting.
| Returns ||
|---|---|
| `boolean` | true if grouping is used
|
**See also:**
- `https://developer.android.com/reference/android/icu/text/NumberFormat#setGroupingUsed(boolean)`
### isParseIntegerOnly
Added in [API level 24](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public boolean 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.
| Returns ||
|---|---|
| `boolean` | true if this will parse integers only
|
### isParseStrict
Added in [API level 24](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public boolean isParseStrict ()
```
**\[icu\]** Returns whether strict parsing is in effect.
| Returns ||
|---|---|
| `boolean` | true if strict parsing is in effect
|
**See also:**
- `https://developer.android.com/reference/android/icu/text/NumberFormat#setParseStrict(boolean)`
### parse
Added in [API level 24](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public Number parse (String text)
```
Parses text from the beginning of the given string to produce a number.
The method might not use the entire text of the given string.
| Parameters ||
|---|---|
| `text` | `String`: A String whose beginning should be parsed.
|
| Returns ||
|---|---|
| `https://developer.android.com/reference/java/lang/Number` | A Number parsed from the string.
|
| Throws ||
|---|---|
| `https://developer.android.com/reference/java/text/ParseException` | if the beginning of the specified string cannot be parsed. |
**See also:**
- `https://developer.android.com/reference/android/icu/text/NumberFormat#format(android.icu.math.BigDecimal)`
### parse
Added in [API level 24](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public abstract Number parse (String text,
ParsePosition parsePosition)
```
Returns a Long if possible (e.g., within the range \[Long.MIN_VALUE,
Long.MAX_VALUE\] and with no decimals); otherwise, returns another type,
such as a BigDecimal, BigInteger, or Double. The return type is not
guaranteed other than for the Long case.
If IntegerOnly is set, will stop at a decimal
point (or equivalent; e.g., for rational numbers "1 2/3", will stop
after the 1).
Does not throw an exception; if no object can be parsed, index is
unchanged!
For more detail on parsing, see the "Parsing" header in the class
documentation of `https://developer.android.com/reference/android/icu/text/DecimalFormat`.
| Parameters ||
|---|---|
| `text` | `String`
|
| `parsePosition` | `ParsePosition`
|

### parseCurrency
Added in [API level 24](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public CurrencyAmount parseCurrency (CharSequence text,
ParsePosition pos)
```
Parses text from the given string as a CurrencyAmount. Unlike
the parse() method, this method will attempt to parse a generic
currency name, searching for a match of this object's locale's
currency display names, or for a 3-letter ISO currency code.
This method will fail if this format is not a currency format,
that is, if it does not contain the currency pattern symbol
(U+00A4) in its prefix or suffix.
| Parameters ||
|---|---|
| `text` | `CharSequence`: the text to parse
|
| `pos` | `ParsePosition`: input-output position; on input, the position within text to match; must have 0 \<= pos.getIndex() \< text.length(); on output, the position after the last matched character. If the parse fails, the position in unchanged upon output.
|
| Returns ||
|---|---|
| `https://developer.android.com/reference/android/icu/util/CurrencyAmount` | a CurrencyAmount, or null upon failure
|
### parseObject

```
Sets the maximum number of digits allowed in the fraction portion of a
number. This must be \>= minimumFractionDigits. If the
new value for maximumFractionDigits is less than the current value
of minimumFractionDigits, then minimumFractionDigits will also be set to
the new value.
| Parameters ||
|---|---|
| `newValue` | `int`: the maximum number of fraction digits to be shown; if less than zero, then zero is used. The concrete subclass may enforce an upper limit to this value appropriate to the numeric type being formatted.
|
**See also:**
- `https://developer.android.com/reference/android/icu/text/NumberFormat#getMaximumFractionDigits()`

```
public void setMinimumFractionDigits (int newValue)
```
Sets the minimum number of digits allowed in the fraction portion of a
number. This must be \<= maximumFractionDigits. If the
new value for minimumFractionDigits exceeds the current value
of maximumFractionDigits, then maximumFractionDigits will also be set to
the new value.
| Parameters ||
|---|---|
| `newValue` | `int`: the minimum number of fraction digits to be shown; if less than zero, then zero is used. Subclasses might enforce an upper limit to this value appropriate to the numeric type being formatted.
|

### setMinimumIntegerDigits
Added in [API level 24](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public void setMinimumIntegerDigits (int newValue)
```
Sets the minimum number of digits allowed in the integer portion of a
number. This must be \<= maximumIntegerDigits. If the
new value for minimumIntegerDigits is more than the current value
of maximumIntegerDigits, then maximumIntegerDigits will also be set to
the new value.
| Parameters ||
|---|---|
| `newValue` | `int`: the minimum number of integer digits to be shown; if less than zero, then zero is used. Subclasses might enforce an upper limit to this value appropriate to the numeric type being formatted.

### setParseIntegerOnly
Added in [API level 24](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public void setParseIntegerOnly (boolean value)
```
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.
| Parameters ||
|---|---|
| `value` | `boolean`: true if this should parse integers only
|
**See also:**
- `https://developer.android.com/reference/android/icu/text/NumberFormat#isParseIntegerOnly()`
### setParseStrict
Added in [API level 24](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public void setParseStrict (boolean value)
```
**\[icu\]** 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.
| Parameters ||
|---|---|
| `value` | `boolean`: True to enable strict parsing. Default is false.
|
