Comment(by zimmerma):
> Here is my point: [...]
ok, I thought you were speaking about the first (smaller) examples. I can
reduce this second
problem to the following:
{{{
sage: R.<x,y> = PolynomialRing(RR)
sage: f=R(1); type(f(0,0))
<type 'sage.rings.real_mpfr.RealNumber'>
sage: f=R(0); type(f(0,0))
<type 'sage.rings.integer.Integer'>
}}}
David, please can you explain why it is so?
