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 WP-34s.
The algorithm used in most HP calculators is similar to the digit-by-digit 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
