[sage-support] cancellation in fraction fields

2010-01-24 Thread Stefan Boettner

Hi, I'm working with fraction fields of multivariate polynomials ring with coefficients in Q. My question is, how do I get cancellation between numerator and denominator coefficients to work? Example: R.=PolynomialRing(QQ, 2) F=FractionField(R) f=(x/2)/(y/2) My question is, how do I get the r
