True if the relative tolerance is met w.r.t. either a or b or if the absolute tolerance is met. Because the relative tolerance is calculated w.r.t. both a and b, this test is symmetric (i.e. neither a nor b is a “reference value”). You have to specify an absolute tolerance if you want to compare to 0.0 because there is no tolerance by default. More information: math.isclose().

numpy.isclose(a, b, rtol=1e-5, atol=1e-8): True if the difference between a and b is less that the sum of the relative tolerance w.r.t. b and the absolute tolerance. Because the relative tolerance is only calculated w.r.t. b, this test is asymmetric and you can think of b as the reference value. Support for comparing sequences is provided by numpy.allclose(). More information: numpy.isclose.

unittest.TestCase.assertAlmostEqual(a, b): True if a and b are within an absolute tolerance of 1e-7. No relative tolerance is considered , so this function is not appropriate for very large or very small numbers. Also, it’s only available in subclasses of unittest.TestCase and it’s ugly because it doesn’t follow PEP8. More information: unittest.TestCase.assertAlmostEqual().

a == pytest.approx(b, rel=1e-6, abs=1e-12): True if the relative tolerance is met w.r.t. b or if the absolute tolerance is met. Because the relative tolerance is only calculated w.r.t. b, this test is asymmetric and you can think of b as the reference value. In the special case that you explicitly specify an absolute tolerance but not a relative tolerance, only the absolute tolerance is considered.
