[sage-support] Question about polynomial rings and their fraction fields

2010-09-24 Thread kcrisman
If I make a polynomial ring using sage: b = PolynomialRing(ZZ, 'x') I get some odd behavior. Namely, sage: bool(b(x)==x) True sage: b(x) x sage: type(b(x)) sage: type(x) This isn't really that odd, but still I don't know whether it is good that one can still use x as a symbolic variable. Pr
