note 60462 added to function.abs

Let's say you are resizing images to a standard size that can be expressed as a ratio (width/height). The problem I came into was that I wanted to be reasonable with the proportion of the images that my customer is uploading (couldn't we all use a little less horizontal on pictures?), but I wanted to reject the horizontal pictures when they were uploading vertical ones. So I wanted to accept proportions of images that were within a reasonable threshold (+ or -) of what I will be resizing them to. Assuming a standard of 1 to 4 (0.25) and a threshold of no more than 0.05 deviation, then the number 0.30 and 0.20 would return true and 0.19 would return false. <?php function threshold($given,$thresh,$standard) { return (abs($given-$standard)<=$thresh) ? true : false; } ?> ---- Manual Page -- http://www.php.net/manual/en/function.abs.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+60462 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+60462&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+60462&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+60462&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+60462&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+60462&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+60462&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+60462&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+60462&report=yes Search -- http://master.php.net/manage/user-notes.php
