Bug #73581 [NEW]: number_format allows for -0.00

From: bowersbros at gmail dot com Operating system: Ubuntu 14.04 PHP version: Irrelevant Package: *General Issues Bug Type: Bug Bug description:number_format allows for -0.00 Description: ------------ number_format fixes the number output from many decimals to a defined number. If you were to have a sufficiently small negative number, it will round and display "-0.00". I'd expect it to become zero, This has already been reported at https://bugs.php.net/bug.php?id=23866 however that is 13 years ago and it has not received a response. Test script: --------------- https://3v4l.org/oU2tg <?php $number = -1.15E-15; var_dump($number); var_dump(number_format($number, 2)); Expected result: ---------------- "0.00" Actual result: -------------- "-0.00" -- Edit bug report at https://bugs.php.net/bug.php?id=73581&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=73581&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=73581&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=73581&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=73581&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=73581&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=73581&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=73581&r=needscript Try newer version: https://bugs.php.net/fix.php?id=73581&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=73581&r=support Expected behavior: https://bugs.php.net/fix.php?id=73581&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=73581&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=73581&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=73581&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=73581&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=73581&r=dst IIS Stability: https://bugs.php.net/fix.php?id=73581&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=73581&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=73581&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=73581&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=73581&r=mysqlcfg
