From documentation of math.fsum:
fsum(seq, /) - Return an accurate floating point sum of values in the iterable seq.
But
>>> import math
>>> vals = [0.1, 0.1, 0.1]
>>> sum(vals)
0.30000000000000004
>>> math.fsum(vals)
0.30000000000000004
or I got it wrong?
(tested in both gnu/linux and windows, python 3.11.1)
