Due to the contribution of Frank Palazzolo, a Windows binary installer and build instructions are available for the clnum package. This also makes ratfun and rpncalc usable on the Windows platform.
The clnum package adds rational numbers and arbitrary precision floating point numbers in real and complex form to Python. It also provides arbitrary precision floating point replacements for the functions in the math and cmath standard library modules. For more information, see Home page: http://calcrpnpy.sourceforge.net/clnum.html -- http://mail.python.org/mailman/listinfo/python-list
