This function formats a number with the given precision. The first options parameter is a space-delimited string of characters to represent negativity, the decimal point, and grouping. The default value is - . ,. The second options parameter defines an alternative delimiting character.
Note that numbers are rounded up at 5 or greater. So, with precision set to 0, 1.5 becomes 2, and 1.4 becomes 1.
