rel_tol is not the correct one to use here. Please read the Python manual carefully or just write the formula explicitly, I don't think there's much of a point to math.isclose.

Did you even test this?

>>> isclose(0.00000000000000001, 0.0, rel_tol=1e-6)
False
``rel_tol`` is not the correct one to use here. Please read the Python manual carefully or just write the formula explicitly, I don't think there's much of a point to ``math.isclose``. Did you even test this? ``` >>> isclose(0.00000000000000001, 0.0, rel_tol=1e-6) False ```

Isn't just == 0.0 sufficient for the purpose explained in the Issue?

Looks like it's quite safe to do so
