note 102848 deleted from function.floor by danbrown

Note Submitter: Joe T. ---- Yet another answer: why make a second function call when you can use basic math operators (or is that what operators secretly do)? function floor_x($number, $x){ return $number - $number % $x; } floor_x(250, 100); // 200 floor_x(23, 20); // 20 floor_x(32, 100); // 0 The modulus gives you the remainder to subtract from the original number. In ex.1, the remainder is 50. In ex.2, it's 3. And in ex.4 it's 32 because 32 / 100 = 0, rem 32.
