Let's do the same comparisons as in the previous Time for action section, but specify a maxulp of 2 when necessary:
Determine the machine epsilon with the
finfo()function:eps = np.finfo(float).eps print("EPS", eps)The epsilon would be as follows:
EPS 2.22044604925e-16Do the comparisons as done in the previous Time for action section, but use the
assert_array_max_ulp()function with the appropriatemaxulpvalue:print("1", np.testing.assert_array_max_ulp(1.0, 1.0 + eps)) print("2", np.testing.assert_array_max_ulp(1.0, 1 + 2 * eps, maxulp=2))1 1.0 2 2.0
