class_docstr: The domain ``ZZ`` representing the integers `\mathbb{Z}`.
  
  The :py:class:`IntegerRing` class represents the ring of integers as a
  :py:class:`~.Domain` in the domain system. :py:class:`IntegerRing` is a
  super class of :py:class:`PythonIntegerRing` and
  :py:class:`GMPYIntegerRing` one of which will be the implementation for
  :ref:`ZZ` depending on whether or not ``gmpy`` or ``gmpy2`` is installed.
