note 100994 added to function.round

Beware strange behaviour if number is negative and precision is bigger than the actual number of digits after comma. round(-0.07, 4); returns -0.07000000000000001 So if you validate it against a regular expression requiring the maximum amount of digits after comma, you'll get into trouble. ---- Server IP: 82.177.164.100 Probable Submitter: 178.73.8.10 ---- Manual Page -- http://www.php.net/manual/en/function.round.php Edit -- https://master.php.net/note/edit/100994 Del: integrated -- https://master.php.net/note/delete/100994/integrated Del: useless -- https://master.php.net/note/delete/100994/useless Del: bad code -- https://master.php.net/note/delete/100994/bad+code Del: spam -- https://master.php.net/note/delete/100994/spam Del: non-english -- https://master.php.net/note/delete/100994/non-english Del: in docs -- https://master.php.net/note/delete/100994/in+docs Del: other reasons-- https://master.php.net/note/delete/100994 Reject -- https://master.php.net/note/reject/100994 Search -- https://master.php.net/manage/user-notes.php
