function fp_truncate_decimals

6.x fp_truncate_decimals($num, $places = 2)
7.x fp_truncate_decimals($num, $places = 2)
4.x fp_truncate_decimals($num, $places = 2)
5.x fp_truncate_decimals($num, $places = 2)

This simple function will take a number and truncate the number of decimals to the requested places. This can be used in place of number_format(), which *rounds* numbers.

For example, number_format(1.99999, 2) gives you 2.00. But THIS function gives: fp_truncate_decimals(1.999999, 2) = 1.99
