* Base class for Tensorflow real numbers data types.

* <p>Real number Tensorflow data types must extend from this class to satisfy compile-time type safety enforced by
* operations that only accept real number tensors as some of their operands. This is asserted by extending the
* generic parameter of those operands from {@link Number}.
*
* <p>Since data types listed under this pacakge are only used for generic parameterization, there is no real data
* manipulation involved. So it is safe to implement the {@link Number} abstract methods by returning zero in all cases.
