Is the step length fixed or does it reduce itself closer to convergence (i.e. sign change)? And how did it calculate the initial guess? You might want to have a look at how to calculate the fast inverse square root. But I must admit that I have no idea whether this is used in the WP34s. The algorithm used in most HP calculators is similar to the digitbydigit method you might have learned at school but uses only addition and shifts. Thus just counting the amount of loops isn't enough if you are interested in performance. Kind regards Thomas
