But the same operation with DECIMAL logarithms (8  8 lg *  10 ln * e^x) gives 16777188. Most probably it uses a similar algorithm, directly placing ln(10) in Z. Thanks for the hint, that is interesting! So the result is a bit closer to the correct 16777216. I still wonder why you would make the calculation more complicated and loose a register for this minor improvement. But I guess that is what they must have done. Cheers, Harald
