## Public methods

### currency

Added in[API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)  

```
public static CurrencyPrecision currency (Currency.CurrencyUsage currencyUsage)
```

Show numbers rounded and padded according to the rules for the currency unit. The most common rounding precision settings for currencies include`Precision.fixedFraction(2)`,`Precision.integer()`, and`Precision.increment(0.05)`for cash transactions ("nickel rounding").

The exact rounding details will be resolved at runtime based on the currency unit specified in the NumberFormatter chain. To round according to the rules for one currency while displaying the symbol for another currency, the withCurrency() method can be called on the return value of this method.

### fixedFraction

Added in[API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)  

```
public static FractionPrecision fixedFraction (int minMaxFractionPlaces)
```

Show numbers rounded if necessary to a certain number of fraction places (numerals after the decimal separator). Additionally, pad with zeros to ensure that this number of places are always shown.

Example output with minMaxFractionPlaces = 3:

87,650.000  
8,765.000  
876.500  
87.650  
8.765  
0.876  
0.088  
0.009  
0.000 (zero)

This method is equivalent to[minMaxFraction(int, int)](https://developer.android.com/reference/android/icu/number/Precision#minMaxFraction(int,%20int))with both arguments equal.

### fixedSignificantDigits

Added in[API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)  

```
public static Precision fixedSignificantDigits (int minMaxSignificantDigits)
```

Show numbers rounded if necessary to a certain number of significant digits or significant figures. Additionally, pad with zeros to ensure that this number of significant digits/figures are always shown.

This method is equivalent to[minMaxSignificantDigits(int, int)](https://developer.android.com/reference/android/icu/number/Precision#minMaxSignificantDigits(int,%20int))with both arguments equal.

### increment

Added in[API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)  

```
public static Precision increment (BigDecimal roundingIncrement)
```

Show numbers rounded if necessary to the closest multiple of a certain rounding increment. For example, if the rounding increment is 0.5, then round 1.2 to 1 and round 1.3 to 1.5.

In order to ensure that numbers are padded to the appropriate number of fraction places, set the scale on the rounding increment BigDecimal. For example, to round to the nearest 0.5 and always display 2 numerals after the decimal separator (to display 1.2 as "1.00" and 1.3 as "1.50"), you can run:  

```
 Precision.increment(new BigDecimal("0.50"))
 
```

**NOTE:** When formatting a*double* , this method, along with[minFraction(int)](https://developer.android.com/reference/android/icu/number/Precision#minFraction(int))and[minSignificantDigits(int)](https://developer.android.com/reference/android/icu/number/Precision#minSignificantDigits(int)), will trigger complex algorithm similar to*Dragon4* to determine the low-order digits and the number of digits to display based on the value of the double. If the number of fraction places or significant digits can be bounded, consider using[maxFraction(int)](https://developer.android.com/reference/android/icu/number/Precision#maxFraction(int))or[maxSignificantDigits(int)](https://developer.android.com/reference/android/icu/number/Precision#maxSignificantDigits(int))instead to maximize performance.
