Guild Wars 2

I was wondering this for a while and while entering in my stats in gw2buildcraft it said my critical chance should be 57.78%, and in-game it shows as 58%

Well, in basic math generally .5 and above is round up, everything below is round down…. so, makes sense to me

The combat probably uses the actual decimal value, and it only rounds for display purposes.

12.44 rounds to 12
12.45 rounds to 12
12.49 rounds to 12
12.50 rounds to 13

I think rising brings up an interesting point..

As far as I have seen, it just uses standard rounding for display purposes, but has it ever been clarified which one the combat engine uses for calculation?

The difference would obviously be rather insignificant (within .5% at most), so it would be rather difficult to parse it out to tell (to say the least). Still would be interested to find out!
