note 71709 added to language.types.integer

Be careful with using the modulo operation on big numbers, it will cast a float argument to an int and may return wrong results. For example: <?php $i = 6887129852; echo "i=$i\n"; echo "i%36=".($i%36)."\n"; echo "alternative i%36=".($i-floor($i/36)*36)."\n"; ?> Will output: i=6.88713E+009 i%36=-24 alternative i%36=20 ---- Server IP: 66.163.161.117 Probable Submitter: 145.116.7.52 ---- Manual Page -- http://www.php.net/manual/en/language.types.integer.php Edit -- https://master.php.net/note/edit/71709 Del: integrated -- https://master.php.net/note/delete/71709/integrated Del: useless -- https://master.php.net/note/delete/71709/useless Del: bad code -- https://master.php.net/note/delete/71709/bad+code Del: spam -- https://master.php.net/note/delete/71709/spam Del: non-english -- https://master.php.net/note/delete/71709/non-english Del: in docs -- https://master.php.net/note/delete/71709/in+docs Del: other reasons-- https://master.php.net/note/delete/71709 Reject -- https://master.php.net/note/reject/71709 Search -- https://master.php.net/manage/user-notes.php
