Fixnum Type
===========

Fixnums are signed integers using two or three bits less than a
machine word, so, roughly +/-\ 2\ :sup:`61` on 64-bit systems and +/-\
2\ :sup:`29` on 32-bit systems.


.. _`fixnum?`:

.. idio:function:: fixnum? o


   test if `o` is a fixnum				
   						
   :param o: object to test			
   :return: ``#t`` if `o` is an fixnum, ``#f`` otherwise	


.. _`FIXNUM-MIN`:

.. idio:value:: FIXNUM-MIN

   :type: fixnum

   The fixnum equivalent of :lname:`C`'s ``INTMIN``.
   

.. _`FIXNUM-MAX`:

.. idio:value:: FIXNUM-MAX

   :type: fixnum

   The fixnum equivalent of :lname:`C`'s ``INTMAX``.
