Always interesting, but I see it needs three multiplications - in modern silicon multiplications are cheap, but as we know, not so cheap on the 6502. We can make them a little cheaper than division, but my belief is that we can do square root with a similar cost to a single division.There is also this method to calculate fp SQRT without any divisions: https://people.eecs.berkeley.edu/~wkaha ... eciprt.pdf
Dave, happy for you to dive in!
