[issue27761] Private _nth_root function loses accuracy

[Steven D'Aprano]

Steven D'Aprano added the comment:

As discussed with Ned via email, this issue shouldn't affect the public geometric_function and the failing tests (currently skipped) are too strict.  The existing tests demand an unrealistic precision which should be loosened,  e.g. from assertEqual to assertAlmostEqual. Ned wrote:

"If you are only planning to make changes to the tests themselves, I think that can wait for b2."

I am currently unable to build 3.6, and I won't have time to resolve that before b1.
