	 * Constructor for a <code>Currency</code> type.
	 *
	 * @class
	 * This class represents the composite type <code>Currency</code>, which consists of the parts
	 * "amount" (of type <code>number</code> or <code>string</code>) and "currency" (of type
	 * <code>string</code>). In case the amount is a <code>string</code>, it must be the JavaScript
	 * representation of the corresponding number.
	 * If the <code>source</code> format option is given, the composite type has only one part of
	 * type <code>string</code>, holding both amount and currency in the source format.
	 *
	 * @extends sap.ui.model.CompositeType
	 *
	 * @author SAP SE
	 * @version ${version}
	 *
	 * @public
	 * @param {object} [oFormatOptions]
	 *   Format options; for a list of all available options, see
	 *   {@link sap.ui.core.format.NumberFormat.getCurrencyInstance}. If the format options
	 *   <code>showMeasure</code> or since 1.89.0 <code>showNumber</code> are set to
	 *   <code>false</code>, model messages for the respective parts are not propagated to the
	 *   control, provided the corresponding binding supports the feature of ignoring model
	 *   messages, see {@link sap.ui.model.Binding#supportsIgnoreMessages}, and the corresponding
	 *   binding parameter is not set manually.
	 * @param {boolean} [oFormatOptions.preserveDecimals=true]
	 *   By default decimals are preserved, unless <code>oFormatOptions.style</code> is given as
	 *   "short" or "long"; since 1.89.0
	 * @param {object} [oFormatOptions.source]
	 *   A set of format options as defined for
	 *   {@link sap.ui.core.format.NumberFormat.getCurrencyInstance} which describes the format of
	 *   amount and currency in the model in case the model holds this in one property of type
	 *   <code>string</code>, e.g. as &quot;EUR 22&quot;. If an empty object is given,
	 *   grouping is disabled, the decimal separator is a dot and the grouping separator is a comma.
	 * @param {object} [oConstraints]
	 *   Constraints for the value part
	 * @param {number} [oConstraints.minimum]
	 *   Smallest amount allowed excluding the minimum value itself
	 * @param {number} [oConstraints.maximum]
	 *   Largest amount allowed excluding the maximum value itself
	 * @alias sap.ui.model.type.Currency
