Now that we're talking about floating point conveniences (math.nan, linspace):
What about putting an
almost_equal(x,y,tol=1e14)
(or close(), or...) in the math module.
AFAICT, in the standard library, there is only:
unittest.TestCase.assertAlmostEqual
but it:
A) is buried in the unittest.TestCase class
B) is an assertion, so you can't use it as a general test (easily)
C) uses number of decimal digits or an absolute delta, but does not provide a significant figures comparison, which is most likely what's wanted (and a bit harder to write yourself)
numpy provides allclose() (and isclose() ), which is pretty much what I'm suggesting.
Anyone else think this would be a good idea to add to the stdlib?
