All Python interpreters use whatever is the C double type on its platform to represent floats. Not all of the platforms use *IEEE-754* floating point types. The most notable and still relevant example that I know of is Cray. -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco -- http://mail.python.org/mailman/listinfo/python-list
