As I understand it, you just want to truncate the number, without rounding. I think you are right, there isn't a function to do it for you but the following code should do it: intval(4.623 * 10)/10 or more generally: function truncate_number($mynumber,$places) { return intval($mynumber * pow(10,$places))/pow(10,$places); }
