assert_array_max_ulp(a, b, maxulp=1, dtype=None)¶
Check that all items of arrays differ in at most N Units in the Last Place.
Input arrays to be compared.
The maximum number of units in the last place that elements of a and b can differ. Default is 1.
Data-type to convert a and b to if given. Default is None.
Array containing number of representable floating point numbers between items in a and b.
If one or more elements differ by more than maxulp.
Compare two arrays relatively to their spacing.
>>> a = np.linspace(0., 1., 100) >>> res = np.testing.assert_array_max_ulp(a, np.arcsin(np.sin(a)))
