In the following, A1 to An are optional batch dimensions.

quaternion A tensor of shape [A1, ..., An, 4], where the last dimension represents a quaternion.
atol The absolute tolerance parameter.
name A name for this op that defaults to "quaternion_is_normalized".

A tensor of type bool and shape [A1, ..., An, 1], where False indicates that the quaternion is not normalized.

ValueError If the shape of quaternion is not supported.
