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 this bug report at https://bugs.php.net/bug.php?id=73581&edit=1
