# number_format

number_format -- format a number with grouped thousands

## Description

`string number_format`(float number, int decimals, string dec_point, string thousands_sep);

number_format() returns a formatted version of `number`. This function accepts either one, two or four parameters (not three):

If only one parameter is given, `number` will be formatted without decimals, but with a comma (",") between every group of thousands.

If two parameters are given, `number` will be formatted with `decimals` decimals with a dot (".") in front, and a comma (",") between every group of thousands.

If all four parameters are given, `number` will be formatted with `decimals` decimals, `dec_point` instead of a dot (".") before the decimals and `thousands_sep` instead of a comma (",") between every group of thousands.
