     *
     * @param value The number to be formatted as currency.
     * @param currencyCode The [ISO 4217](https://en.wikipedia.org/wiki/ISO_4217) currency code,
     * such as `USD` for the US dollar and `EUR` for the euro. The default currency code can be
     * configured using the `DEFAULT_CURRENCY_CODE` injection token.
     * @param display The format for the currency indicator. One of the following:
     *   - `code`: Show the code (such as `USD`).
     *   - `symbol`(default): Show the symbol (such as `$`).
     *   - `symbol-narrow`: Use the narrow symbol for locales that have two symbols for their
     * currency.
     * For example, the Canadian dollar CAD has the symbol `CA$` and the symbol-narrow `$`. If the
     * locale has no narrow symbol, uses the standard symbol for the locale.
     *   - String: Use the given string value instead of a code or a symbol.
     * For example, an empty string will suppress the currency & symbol.
     *   - Boolean (marked deprecated in v5): `true` for symbol and false for `code`.
     *
     * @param digitsInfo Decimal representation options, specified by a string
     * in the following format:<br>
     * <code>{minIntegerDigits}.{minFractionDigits}-{maxFractionDigits}</code>.
     *   - `minIntegerDigits`: The minimum number of integer digits before the decimal point.
     * Default is `1`.
     *   - `minFractionDigits`: The minimum number of digits after the decimal point.
     * Default is `2`.
     *   - `maxFractionDigits`: The maximum number of digits after the decimal point.
     * Default is `2`.
     * If not provided, the number will be formatted with the proper amount of digits,
     * depending on what the [ISO 4217](https://en.wikipedia.org/wiki/ISO_4217) specifies.
     * For example, the Canadian dollar has 2 digits, whereas the Chilean peso has none.
     * @param locale A locale code for the locale format rules to use.
     * When not supplied, uses the value of `LOCALE_ID`, which is `en-US` by default.
     * See [Setting your app locale](guide/i18n#setting-up-the-locale-of-your-app).
