Summary0004471: Add more math functions to Decorate
DescriptionI mean

FRandomPick(float[]), RandomPick(int[]),

Cos(float), Sin(float), Tan(float),

ACos(float), ASin(float), ATan(float),

ATan2(float, float) [Alias: VectorAngle(float, float)],

Round(float), Ceil(float), Floor(float),

Min(float[]), Max(float[]), Clamp(float, float, float).

I think it will be easy to implement these functions in Decorate, because C\C++ already has libraries that calculate these functions (except #randompick(#[])).

And RandomPick is actually many times more necessary than trigonometry and rounding, because here is a comparison of the same function but only using RandomPick and Random

GZdoom: RandomPick(64, 192)
Za: (128 + ((Random(0, 1)*2)-1)*64)

And this way every function call imitation, the optimization after 3-8 repeats per tic goes somewhere far away...

This won't happen until we upgrade our GZDoom base and backport these functions, which won't be until at least 4.0 or later.
