Because math.pow returns a float; 100 ** 155 won't fit in a float.
Sure that is the reason.
May I rephrase, my question:
Why not returning another type as long as we can calculate it?
After all, math module is likely to be used on large numbers as well.
Because it's very complicated to get it right. The math module is a thin
wrapper around the platform math library. It took Mark and me very long
to get cmath and math right for floats (C doubles). Arbitrary precision
and arbitrary length numbers are a different story. You have to use 3rd
party tools for those. The standard library aims to solve common
problems, not special problems.
