class_docstr: Integer ring based on Python's ``int`` type.
  
  This will be used as :ref:`ZZ` if ``gmpy`` and ``gmpy2`` are not
  installed. Elements are instances of the standard Python ``int`` type.
docstr: Convert ``a`` to a SymPy object. 
docstr_tok: ["Convert","``","a","``","to","a","SymPy","object","."]
code: def to_sympy(self, a):
      """Convert ``a`` to a SymPy object."""
      return SymPyInteger(a)
