You replied two times making statements about something you don't know, this is very frustrating.
Please stop doing so, please triple check your statements before clicking the submit button.
And you don't make mistakes? I've seen you do so as well. So don't be rude. Yes, I should have checked other numbers, but as it only said that $calc and /var were different for those two examples, I didn't think to. If the post had ignored $calc altogether and just said that /var %a = 4 % 0 and /var %a = 4 % 2 don't calculate the same, the mistake wouldn't have been made. In any case, being rude about a mistake doesn't help anything.
@argv0 - Ok, I tested just the original examples, which didn't mention it worked without it being 0. With clarifying that it works without 0, then yes, it's a bug.
