note 102848 added to function.floor

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. ---- Server IP: 69.147.83.197 Probable Submitter: 76.235.204.165 ---- Manual Page -- http://www.php.net/manual/en/function.floor.php Edit -- https://master.php.net/note/edit/102848 Del: integrated -- https://master.php.net/note/delete/102848/integrated Del: useless -- https://master.php.net/note/delete/102848/useless Del: bad code -- https://master.php.net/note/delete/102848/bad+code Del: spam -- https://master.php.net/note/delete/102848/spam Del: non-english -- https://master.php.net/note/delete/102848/non-english Del: in docs -- https://master.php.net/note/delete/102848/in+docs Del: other reasons-- https://master.php.net/note/delete/102848 Reject -- https://master.php.net/note/reject/102848 Search -- https://master.php.net/manage/user-notes.php
