note 18062 added to function.sprintf

The 'e' format specifier is not documented. However, it seems to work, but without showing the exponential part of the number. This is a function to get the scientific representation of a number: function sci($x, $d=-1) { $e=floor(log10($x)); $x*=pow(10,-$e); $fmt=($d>=0)?".".$d:""; $e=($e>=0)?"+".sprintf("%02d",$e):"-".sprintf("%02d",-$e); return sprintf("%".$fmt."fe%s",$x,$e); } It takes the number as the first parameter and the precision as the second. The precision is optional. The default precision for the 'f' format specifier is used if no precision is specified. -- http://www.php.net/manual/en/function.sprintf.php http://master.php.net/manage/user-notes.php?action=edit+18062 http://master.php.net/manage/user-notes.php?action=delete+18062 http://master.php.net/manage/user-notes.php?action=reject+18062
