Equivalent of evalf for numeric (for fractions)

[Eduardo M Kalinowski]

Hi again,

    How can I convert a GiNaC::numeric that contains a fraction (or even
a integer, for that matter) into a numeric with the real representation
of the fraction? Currently I'm adding "0.0" to the numeric to force it
into a real number. This works, but is ugly. How about an "evalf"
function for GiNaC::numeric?
