Re: Fix division by zero to throw exception (round 2)

I would like to bring this topic back up, as there were users confused with it and it's absolutely not consistent what we have now. See also https://bugs.php.net/bug.php?id=69957 <https://bugs.php.net/bug.php?id=69957> (As I thought it was non-intentional, I went ahead and "fixed" it, was reverted later, hence discussing that now here.) So, looks like there was some quick decisions and discussion I totally had missed. What we have now is: > Am 03.04.2015 um 23:13 schrieb Dmitry Stogov <dmitry@zend.com>: > > So the summary: > > 1) division by zero produces a warning and +/-INF IS_DOUBLE.

Why does 0 % 0 throw an Exception, but 0 / 0 NAN? Why does 1 % 0 throw an Exception, but 1 / 0 INF? I'd like to either properly return 0, INF or NAN in both cases or in none. Having different rules for so similar operations is non-sense, I think. It just is inconsistent and causes confusion. Bob
