* @param float $value Money amount.

* can also set this to false to hide the currency symbol.
*
* @param integer $precision For some reason, if you need some precision
* other than 2 decimal places, you can modify this value. You probably
* won't need to do this unless, for example, you want to round to the
* nearest dollar (set the precision to 0).
*
* @param string $grouping This value is used internally as the
* NumberFormatter::GROUPING_USED value when using PHP's NumberFormatter
* class. Its documentation is non-existent, but it appears that if you set
* this to true, numbers will be grouped with a comma or period (depending
* on your locale): 12345.123 would display as 12,345.123.
*
* @param integer $divisor If, for some reason, you need to divide your
* starting value by a number before rendering it to the user, you can use
* the divisor option.
*
* @return string Localized money
