## Public constructors

### Builder

Added in[1.0.0](https://developer.android.com/jetpack/androidx/releases/wear-protolayout#1.0.0)  

```
Builder()
```  

## Public functions

### build

Added in[1.0.0](https://developer.android.com/jetpack/androidx/releases/wear-protolayout#1.0.0)  

```
fun build(): DynamicBuilders.DynamicFloat.FloatFormatter
```

Builds an instance with values accumulated in this Builder.  

### setGroupingUsed

Added in[1.0.0](https://developer.android.com/jetpack/androidx/releases/wear-protolayout#1.0.0)  

```
@RequiresSchemaVersion(major = 1, minor = 200)
fun setGroupingUsed(groupingUsed: Boolean): DynamicBuilders.DynamicFloat.FloatFormatter.Builder
```

Sets whether grouping is used for the formatter. Defaults to false if not specified. If grouping is used, digits will be grouped into digit groups using a separator. Digit group size and used separator can vary in different countries/regions. As an example, for locale en_US, the following is equal to`* DynamicString.constant("1,234")`  

```kotlin
  DynamicFloat.constant(1234)
      .format(
          new FloatFormatter.Builder()
                          .setGroupingUsed(true).build());
```  

### setMaxFractionDigits

Added in[1.0.0](https://developer.android.com/jetpack/androidx/releases/wear-protolayout#1.0.0)  

```
@RequiresSchemaVersion(major = 1, minor = 200)
fun setMaxFractionDigits(maxFractionDigits: @IntRange(from = 0) Int): DynamicBuilders.DynamicFloat.FloatFormatter.Builder
```

Sets maximum number of fraction digits for the formatter. Defaults to three if not specified. minimumFractionDigits must be \<= maximumFractionDigits. If the condition is not satisfied, then minimumFractionDigits will be used for both fields.  

### setMinFractionDigits

Added in[1.0.0](https://developer.android.com/jetpack/androidx/releases/wear-protolayout#1.0.0)  

```
@RequiresSchemaVersion(major = 1, minor = 200)
fun setMinFractionDigits(minFractionDigits: @IntRange(from = 0) Int): DynamicBuilders.DynamicFloat.FloatFormatter.Builder
```

Sets minimum number of fraction digits for the formatter. Defaults to zero if not specified. minimumFractionDigits must be \<= maximumFractionDigits. If the condition is not satisfied, then minimumFractionDigits will be used for both fields.  

### setMinIntegerDigits

Added in[1.0.0](https://developer.android.com/jetpack/androidx/releases/wear-protolayout#1.0.0)  

```
@RequiresSchemaVersion(major = 1, minor = 200)
fun setMinIntegerDigits(minIntegerDigits: @IntRange(from = 0) Int): DynamicBuilders.DynamicFloat.FloatFormatter.Builder
```

Sets minimum number of integer digits for the formatter. Defaults to one if not specified. If minIntegerDigits is zero and the -1\<1, the Integer part will not appear.
