note 93195 added to function.abs

27-Aug-09 Anonymous - be aware that multiplying by -1 turns negative numbers positive, but doesn't protect against being passed a positive number by mistake. You may also want to check and make sure you don't inadvertently lose precision (this is a problem in other languages), and keep an eye out for underflow/overflow. The ABS function does that for you. ---- Server IP: 208.69.120.35 Probable Submitter: 71.0.86.226 ---- Manual Page -- http://www.php.net/manual/en/function.abs.php Edit -- https://master.php.net/note/edit/93195 Del: integrated -- https://master.php.net/note/delete/93195/integrated Del: useless -- https://master.php.net/note/delete/93195/useless Del: bad code -- https://master.php.net/note/delete/93195/bad+code Del: spam -- https://master.php.net/note/delete/93195/spam Del: non-english -- https://master.php.net/note/delete/93195/non-english Del: in docs -- https://master.php.net/note/delete/93195/in+docs Del: other reasons-- https://master.php.net/note/delete/93195 Reject -- https://master.php.net/note/reject/93195 Search -- https://master.php.net/manage/user-notes.php
