/**
 * A decimal field that stores the value as a string rather than a `number` to support better precision.
 *
 * This class accepts all the props of [NumberField](doc:NumberField) as well as the optional
 * `decimalPlaces` properties which can be used by form widgets to limit the accepted values.
 *
 * <Usage>
 * Use with [viewModelFactory](doc:viewModelFactory).
 *
 * ```js
 * viewModelFactory({
 *   id: new Field(),
 *   total: new DecimalField(),
 * }, { pkFieldName: 'id' });
 * ```
 *
 * Optionally provide `minValue`, `maxValue`, `decimalPlaces` or any options from [Field](doc:Field):
 *
 * ```js
 * viewModelFactory({
 *   id: new Field(),
 *   total: new CharField({
 *     minValue: '0',
 *     decimalPlaces: 2,
 *   }),
 * }, { pkFieldName: 'id' });
 * ```
 *
 * <Alert type="info">
 * To support decimal operations consider a custom implementation that uses a decimal library eg. decimal.js
 * </Alert>
 *
 * See also: [FloatField](doc:FloatField)
 *
 * </Usage>
