Web$\begingroup$ Also, I may have missed some of your edits, but I managed to implement 2^z by splitting it into 2^{i.f} = 2^i * 2^{0.f}, where i is the integer portion and f is the fractional portion. 2^i is simple, just bit manipulation, and 2^{0.f} had a limited range, so it lent itself well to LUT with interpolation. I also handled the negative case: 2^{-i.f} = 2^{-i} * 1/(2^{0.f}.
