note 83910 added to function.abs

I think there are faster methods for doing an on/off. $value = (1 - $value); or better: $value = (1 ^ $value); // which uses the xor function. Below are the benchs on my computer, for loop of 10,000,000 with PHP Version 5.2.1 $value = abs($value -1); // 4.12641406059 sec $value = (1 - $value); // 1.58847904205 sec $value = (1 ^ $value); // 1.49518704414 sec Note that using function call for such operation is very slow. function on_off($value) { return (1 ^ $value); } // 7.10739612579 sec ---- Server IP: 195.207.10.20 Probable Submitter: 194.78.219.251 ---- Manual Page -- http://www.php.net/manual/en/function.abs.php Edit -- https://master.php.net/note/edit/83910 Del: integrated -- https://master.php.net/note/delete/83910/integrated Del: useless -- https://master.php.net/note/delete/83910/useless Del: bad code -- https://master.php.net/note/delete/83910/bad+code Del: spam -- https://master.php.net/note/delete/83910/spam Del: non-english -- https://master.php.net/note/delete/83910/non-english Del: in docs -- https://master.php.net/note/delete/83910/in+docs Del: other reasons-- https://master.php.net/note/delete/83910 Reject -- https://master.php.net/note/reject/83910 Search -- https://master.php.net/manage/user-notes.php
