note 107492 added to function.number-format

I was looking for a way to format a number to a certain number of significant digits, instead of decimal points. This is what I came up with: function number_significant($x, $n) { $x_sci = sprintf("%.".$n."e", $x); $x_f = rtrim(sprintf("%f", $x_sci),"0"); if ( $x_f[strlen($x_f)-1]=="." ) { $x_f .= "0"; } return $x_f; } ---- Server IP: 69.147.83.197 Probable Submitter: 50.76.186.161 ---- Manual Page -- http://www.php.net/manual/en/function.number-format.php Edit -- https://master.php.net/note/edit/107492 Del: integrated -- https://master.php.net/note/delete/107492/integrated Del: useless -- https://master.php.net/note/delete/107492/useless Del: bad code -- https://master.php.net/note/delete/107492/bad+code Del: spam -- https://master.php.net/note/delete/107492/spam Del: non-english -- https://master.php.net/note/delete/107492/non-english Del: in docs -- https://master.php.net/note/delete/107492/in+docs Del: other reasons-- https://master.php.net/note/delete/107492 Reject -- https://master.php.net/note/reject/107492 Search -- https://master.php.net/manage/user-notes.php
