## Public constructors

### Builder

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

```
public Builder()
```

## Public methods

### build

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

```
public @NonNull DynamicBuilders.DynamicFloat.FloatFormatter build()
```

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)
public @NonNull DynamicBuilders.DynamicFloat.FloatFormatter.Builder setGroupingUsed(boolean groupingUsed)
```

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")`

```
  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)
public @NonNull DynamicBuilders.DynamicFloat.FloatFormatter.Builder setMaxFractionDigits(@IntRange(from = 0) int maxFractionDigits)
```

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)
public @NonNull DynamicBuilders.DynamicFloat.FloatFormatter.Builder setMinFractionDigits(@IntRange(from = 0) int minFractionDigits)
```

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)
public @NonNull DynamicBuilders.DynamicFloat.FloatFormatter.Builder setMinIntegerDigits(@IntRange(from = 0) int minIntegerDigits)
```

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.
