Sometimes Pathfinder does things so simply they become stupid. For example, with temporary ability bonuses or damage (see here ), every 2 points (positive or negative) creates a temporary modifier, regardless of the score value. I think most people just ignore this and pretend it adds to the ability score, which follows more sane rules (and creates a tiny, tiny reason to allow odd scores on your sheet). Also I'm pretty sure 3.5 did that. But an interesting fact - I'm not sure there's a way, using roll20 math, to achieve this type of rounding. You can't just use floor or ceil, as that'll have the wrong effect at -odd or +odd, respectively. You can't use round, roll20 uses the "round toward positive infinity" convention, rather than the "round toward 0" convention that one would need in this case. I've tried playing around with the new abs() function, doing things like "x/abs(x)" to get the sign of x and then subtract say 0.1 with that sign, which would do what I need it to do (aside, of course, from being INCREDIBLY ugly - but yeah inline rolls. But that doesn't work if the temp modifier is zero...which is probably the single most-common use-case. Ideas? I know Roll20 is designed to be platform-agnostic, but it'd be really nice to have the ability, however one could do it, to round this "correctly". Edit: I'm an idiot and x/abs(x) only tries to work if you are in API-land or using scalars like I was for testing - won't work for macro rolls. Edit2: I'm really an idiot and added that last edit, when in fact we were looking at attribute-based things here, where x/abs(x) would work. Regardless, solution down below.
