ValueError: Out of domain for acos

The above exception was the direct cause of the following exception:

    def test_math_util_length_domain():
        with pytest.raises(ValueError):

    def length(A, B):
        r"""
        Returns the angular distance between two points (in vector space)
        on the unit sphere.

        Parameters
        ----------
        A, B : (*x*, *y*, *z*) triples or Nx3 arrays of triples
           The endpoints of the great circle arc, in vector space.

        Returns
        -------
        length : scalar or array of scalars
            The angular length of the great circle arc in radians.

        Notes
        -----
        The length is computed using the following:

        .. math::

           \Delta = \arccos(A \cdot B)
