Furthermore, if you consistently don't clear common content from your numerator/denominator pairs you can end up with quite bad coefficient blow-up.
Of course, the work-around is to use Z['x'].fraction_field(). -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
