note 106560 added to function.number-format

To prevent the rounding that occurs when next digit after last significant decimal is 5 (mentioned by several people below): <?php function fnumber_format($number, $decimals='', $sep1='', $sep2='') { if (($number * pow(10 , $decimals + 1) % 10 ) == 5) //if next not significant digit is 5 $number -= pow(10 , -($decimals+1)); return number_format($number, $decimals, $sep1, $sep2); } $t=7.15; echo $t . " | " . number_format($t, 1, '.', ',') . " | " . fnumber_format($t, 1, '.', ',') . "\n\n"; //result is: 7.15 | 7.2 | 7.1 $t=7.3215; echo $t . " | " . number_format($t, 3, '.', ',') . " | " . fnumber_format($t, 3, '.', ',') . "\n\n"; //result is: 7.3215 | 7.322 | 7.321 } ?> have fun! ---- Server IP: 69.147.83.197 Probable Submitter: 86.120.176.120 ---- Manual Page -- http://www.php.net/manual/en/function.number-format.php Edit -- https://master.php.net/note/edit/106560 Del: integrated -- https://master.php.net/note/delete/106560/integrated Del: useless -- https://master.php.net/note/delete/106560/useless Del: bad code -- https://master.php.net/note/delete/106560/bad+code Del: spam -- https://master.php.net/note/delete/106560/spam Del: non-english -- https://master.php.net/note/delete/106560/non-english Del: in docs -- https://master.php.net/note/delete/106560/in+docs Del: other reasons-- https://master.php.net/note/delete/106560 Reject -- https://master.php.net/note/reject/106560 Search -- https://master.php.net/manage/user-notes.php
