An issue occurs when running the following code. 

import math
math.fsum([0.1, 0.2]), math.fsum([0.1, 0.7])

This should output 0.3, 0.8 respectively.

Instead, it output 0.30000000000000004, 0.7999999999999999

The very floating-point error it is trying to stop from occurring.

Thank you for your time.
