There are two questions, really: 1) why does gcd(2/3, 4/9) give 2/9 instead of (the greater) 2/3? I know what the code is doing...but should it be doing that? I read that

But why should it yield an integer; you started with fractions, I would expect to only end with integers if one number was an integer multiple of the other, which 2/3 and 4/9 are not -- they are powers of each other. 2) regardless of the answer to 1, perhaps terms_gcd could get the option to not clear the denominators? But on the other hand, why would you want to keep the fractions? Hmm.. -- You received this message because you are subscribed to the Google Groups "sympy" group.
