/* global CURRENCY, Intl */
/** 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.
*
* @memberof Formatters
* @param {number} value - The value to operate on
* @param {string} type - One of `'integer'`, `'percent'` , `'currency'`, or `/currency:[A-Z]{3}/`
*
* @example
* var mf = new MessageFormat('en');
* mf.currency = 'EUR'; // needs to be set before first compile() call
*
* 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.'
