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, barray_like
-
Input arrays to be compared.
-
maxulpint, optional
-
The maximum number of units in the last place that elements of
a
andb
can differ. Default is 1. -

a
andb
