The math module documentation says:

   Except when explicitly noted otherwise, all return values are floats.

But this code returns an integer:

   from math import prod; prod((1,2,3))

Doc should "explicitly note otherwise" here, I imagine. The issue being wanting to know that the result on all-integer input will be an exact (integer) value not a floating value.

I'll add a note that the output type is determined by the input type.
