note 114061 added to function.is-numeric

Apparently NAN (Not A Number) is a number for the sake of is_numeric(). <?php echo "is "; if (!is_numeric(NAN)) echo "not "; echo "a number"; ?> Outputs "is a number". So something that is NOT a number (by defintion) is a number... ---- Server IP: 72.52.91.14 Probable Submitter: 72.52.91.14 ---- Manual Page -- http://php.net/manual/en/function.is-numeric.php Edit -- https://master.php.net/note/edit/114061 Del: integrated -- https://master.php.net/note/delete/114061/integrated Del: useless -- https://master.php.net/note/delete/114061/useless Del: bad code -- https://master.php.net/note/delete/114061/bad+code Del: spam -- https://master.php.net/note/delete/114061/spam Del: non-english -- https://master.php.net/note/delete/114061/non-english Del: in docs -- https://master.php.net/note/delete/114061/in+docs Del: other reasons-- https://master.php.net/note/delete/114061 Reject -- https://master.php.net/note/reject/114061 Search -- https://master.php.net/manage/user-notes.php
