This may be true, however when number_format returns -0.00 this is not a valid number. The evidence that you can use to derive such number is no longer available to you. When using number_format for display which is the intent of number_format is used for -0.00 is not valid. I realize that the intent of number_format is to format numbers, but I do not think however that it should return numbers that can not possibly exist in the numeric system. Please reconsider your evaluation.

Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php there is, -0.0000000000000000001E-999 is about -0. Floating points are never precise, -0 is therefore possible. ------------------------------------------------------------------------ [2003-05-28 16:41:56] david at ewebdevelopers dot com $num = -1.3322676295502E-015; echo number_format($num, 2, '.', ','); if(((float) number_format(($num, 2,'.', ',')) == 0){ echo 'true'; } number_format should not evaluate to -0.00 should evaluate to 0.00 because there is no such thing as -0; ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=23866&edit=1
