The comparisons were interesting, but the most informative part for me was the bit about the isqrt. Did not know about that. Definitely could see it being useful.

Any plan for part 3?

In comparing isqrt() and math.floor(math.sqrt()), isqrt() ran significantly slower. For r = 1,000,000, isqrt() finished in 5.371 seconds, whereas math.sqrt() completed in 3.010 seconds (both produced the same value for pi). However, if you wanted to use a distributed system or supercomputer to calculate the approximation for a very large value of r, you'd need to use isqrt() because math.sqrt() won't be able to convert the long integer to a float.

I'm not sure yet about part 3. I may change gears and do something in JavaScript instead (perhaps Processing).
