I'm using Log+Exp functions bundle to perform pow() function on my image. When working with zero pixels, log(0) returns -Inf and exp(-Inf) retuns zero, so the result is correct. However, if _EM_INVALID flag in floating-point control word is unmasked, exception "0xC00002B5: Multiple floating point traps" is thrown.
I do not expect this exception, since no NaN is actually in game. For now I masked this flag during the call of ippiExp_32f_C3IR(), but I want proper behavior.
