I'm looking for a way to create a symbolic rational variable--it must be
possible, right? I want to do something like this:
R = PolynomialRing(QQ,'x');S.a=R.quotient(x^3+x+1);S1.y = S[];
(y^3+y+1)(y=a);
var('b1 b2 b3')
(b1+b2*a+b3*a^2)^2
and get

Namely, create expressions mixing rational variables and elements of a
quotient field over the rationals.

Doing something like this:
(3/4)*a
is fine, but the b*a, gives me

Hello!
I have the following problem, and I do not know whether it is a bug
or a supposed behaviour.
I upload a C program to my worksheet and compile it using the
server's GCC with this command:
os.system(cd +DATA+ gcc infinite_cycle.c -o infinite_cycle.bin)
Than I start the obtained
Thanks!

Dear Álinson,
This is now fixed in the new release sage-6.5
sage: xgcd(4,2)
(2, 0, 1)
sage: xgcd(Rational(4),Rational(2))
(2, 0, 1)
But be careful that the output type depends on the input
sage: a,b,c = xgcd(4,2)
sage: d,e,f = xgcd(Rational(4), Rational(2))
sage: type(a), type(b), type(c)
I'm trying the monkey solution of building from source... I have little
hope that it will work, but who knows?

Hi
I have no idea how to solve this. If you create and log in as a different
user, does it have the same problem?
(I can confirm my PPA installs do not show this error)
It might also help to ask on an ipython list (but mention that you get this
in sage).
Or install ipython from
