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.
- a, barray_like
Input arrays to be compared.
- maxulpint, optional
The maximum number of units in the last place that elements of a and b can differ. Default is 1.
- dtypedtype, optional
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.
For computing the ULP difference, this API does not differentiate between various representations of NAN (ULP difference between 0x7fc00000 and 0xffc00000 is zero).
>>> a = np.linspace(0., 1., 100) >>> res = np.testing.assert_array_max_ulp(a, np.arcsin(np.sin(a)))
