rational functions

[Ricardo Guzman]

Hello-

    How does ginac handle rational expressions internally? I see how
polynomials in general are represented through the 'expairseq' framework.
But, how does it manipulate a quotient of two polynomials in the case of gcd
calculations or when querying for numerator/denominator?

    Thanks in advance,

Ricardo
