/**
 * Represent a number as an integer, percent or currency value
 *
 * Available in MessageFormat strings as `{VAR, number, integer|percent|currency}`.
 * Internally, calls Intl.NumberFormat with appropriate parameters. `currency` will
 * default to USD; to change, set `MessageFormat#currency` to the appropriate
 * three-letter currency code, or use the `currency:EUR` form of the argument.
 *
 * @example
 * ```js
 * var mf = new MessageFormat('en', { currency: 'EUR'});
 *
 * mf.compile('{N} is almost {N, number, integer}')({ N: 3.14 })
 * // '3.14 is almost 3'
 *
 * mf.compile('{P, number, percent} complete')({ P: 0.99 })
 * // '99% complete'
 *
 * mf.compile('The total is {V, number, currency}.')({ V: 5.5 })
 * // 'The total is €5.50.'
 *
 * mf.compile('The total is {V, number, currency:GBP}.')({ V: 5.5 })
 * // 'The total is £5.50.'
 * ```
