note 21954 added to function.sprintf

Previously submitted sci() function to get scientific representation of a number is not working with 0 and negative numbers. So, here is the modified version: function sci($x, $d=-1) { $min=($x<0)?"-":""; $x=abs($x); $e=floor(($x!=0)?log10($x):0); $x*=pow(10,-$e); $fmt=($d>=0)?".".$d:""; $e=($e>=0)?"+".sprintf("%02d",$e):"-".sprintf("%02d",-$e); return sprintf("$min%".$fmt."fe%s",$x,$e); } -- http://www.php.net/manual/en/function.sprintf.php http://master.php.net/manage/user-notes.php?action=edit+21954 http://master.php.net/manage/user-notes.php?action=delete+21954 http://master.php.net/manage/user-notes.php?action=reject+21954
