Hi there. I've been looking at the behaviour of the round functionality in PHP. We're currently still using v4.2.3, (but the documentation seems to suggest it's the same for versions after this).
Doing the following rounds always rounds *up* to the nearest whole number. i.e. 0.5 => 1 1.5 => 2 2.5 => 3 3.5 => 4 In earlier PHP docs, it stated that halves would be rounded to the nearest even number. i.e. 3.5 => 4 4.5 => 4 When did this change. Or is this *actually* the case in a version of PHP later than 4.2.3. I've had a look at the PHP changelog and the bug lists and found nothing. :( I know I can work around this by adding a fuzz factor, but I'd rather not. I'm just confused as to why something so fundamental to math would change across PHP versions.
