note 81951 added to function.round

Regarding the change of behavior where round now returns certain values in exponential notation, here's a second way this can bite you. If you have field validation code like below, this will falsely indicate an error when the consumer enters one of the "special" values for income, e.g., 1200000, which is returned as "1.2E+6": if(!ereg("^[0-9]{1,10}$", round($_POST['income']))) { $errors .= "<li>Income should be whole dollars only (10 digits max).</li>"; } Needless to say, not a good user experience. ---- Server IP: 208.69.120.35 Probable Submitter: 12.7.177.130 ---- Manual Page -- http://www.php.net/manual/en/function.round.php Edit -- https://master.php.net/note/edit/81951 Del: integrated -- https://master.php.net/note/delete/81951/integrated Del: useless -- https://master.php.net/note/delete/81951/useless Del: bad code -- https://master.php.net/note/delete/81951/bad+code Del: spam -- https://master.php.net/note/delete/81951/spam Del: non-english -- https://master.php.net/note/delete/81951/non-english Del: in docs -- https://master.php.net/note/delete/81951/in+docs Del: other reasons-- https://master.php.net/note/delete/81951 Reject -- https://master.php.net/note/reject/81951 Search -- https://master.php.net/manage/user-notes.php
