#40802 [NEW]: number_format does not fill rounded number with zeros

From: taco at procurios dot nl Operating system: Linux 2.6.17-11-386 PHP version: 5.2.1 PHP Bug Type: *Math Functions Bug description: number_format does not fill rounded number with zeros Description: ------------ Since there is no way to tell number_format to use a specified decimal separator and thousands separator without rounding the number I wanted to set the amount of decimals bigger than the given amount of decimals to strip the trailing zeros afterwards. However, the string number_format returned did not only add zeros to the given number: $ php -v PHP 5.2.1-0.dotdeb.1 with Suhosin-Patch 0.9.6.2 (cli) (built: Feb 9 2007 04:46:32) Copyright (c) 1997-2007 The PHP Group Zend Engine v2.2.0, Copyright (c) 1998-2007 Zend Technologies $ php -r "echo number_format(2.333333, 60, ',', '.');" 2,333333000000000101437080957111902534961700439453125000000000 Reproduce code: --------------- echo number_format(2.333333, 60, ',', '.'); Expected result: ---------------- 2,333333000000000000000000000000000000000000000000000000000000 Actual result: -------------- 2,333333000000000101437080957111902534961700439453125000000000 -- Edit bug report at http://bugs.php.net/?id=40802&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=40802&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=40802&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=40802&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=40802&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=40802&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=40802&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=40802&r=needscript Try newer version: http://bugs.php.net/fix.php?id=40802&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=40802&r=support Expected behavior: http://bugs.php.net/fix.php?id=40802&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=40802&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=40802&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=40802&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=40802&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=40802&r=dst IIS Stability: http://bugs.php.net/fix.php?id=40802&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=40802&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=40802&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=40802&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=40802&r=mysqlcfg
