The Decimal type does not represents numbers as fractions, it represents them as decimal floating point, i.e. a floating point representation using base 10 instead of base 2. A fractions module was introduced in Python 2.6 that does represent numbers as a numerator and denominator: http://docs.python.org/library/fractions.html Kent _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
