note 59750 added to function.trim

Using "trim" to minimize the format of a decimal number strikes me as awkward. I would just use: $str += 0; This even has the added benefit of ensuring that you have at least one digit (and thus have a valid number) even if the original was empty. ---- Manual Page -- http://www.php.net/manual/en/function.trim.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+59750 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+59750&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+59750&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+59750&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+59750&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+59750&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+59750&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+59750&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+59750&report=yes Search -- http://master.php.net/manage/user-notes.php
