numpy.testing.assert_array_max_ulp¶

numpy.testing.assert_array_max_ulp(a,b,maxulp=1,dtype=None)[source]¶

Check that all items of arrays differ in at most N Units in the Last Place.

Parameters:	a, b : array_like Input arrays to be compared. maxulp : int, optional The maximum number of units in the last place that elements ofa andb can differ. Default is 1. dtype : dtype, optional Data-type to converta andb to if given. Default is None.
Returns:	ret : ndarray Array containing number of representable floating point numbers betweenitems ina andb.
Raises:	AssertionError If one or more elements differ by more thanmaxulp.
