as sqrtf(0) gives us nan as result and  IUMAX(1e-6f,a) and IUMAX(a,1e-6f) give different results when a=nan we do some sanity checks if one of the arguments given to IUMAX or IUMIN is nan or inf -> then automatically the other value is taken.

absolutely no clue why switching the order of the arguments changes the result....
