Previous Comments: ------------------------------------------------------------------------ [2015-03-02 16:01:29] tom at r dot je Description: ------------ It's possible to get a signed zero: <?php echo round(-0.0001, 2); // -0 ?> This is valid according to IEEE 754 so probably shouldn't be changed internally. However, for display purposes, "-0" is needlessly confusing. There's no simple way of removing it. I can call abs($num) but I need an if statement to only call abs($num); when $num is -0. My proposal is that number_format, which is used for display purposes, changes -0 into +0. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=69161&edit=1
