Old description:
> {{{
> sage: P=PolynomialRing(RR,'z')
> sage: z=P.gen()
> sage: binomial(z,2)
> (z^2 - z)/2.00000000000000
> }}}
> One would expect here to get the polynomial `0.5*z^2-0.5*z`
New description:
{{{
sage: P=PolynomialRing(RR,'z')
sage: z=P.gen()
sage: binomial(z,2)
(z^2 - z)/2.00000000000000
}}}
One would expect here to get the polynomial `0.5*z^2-0.5*z`

Comment:
In the documentation, the line
{{{
Test symbolic and uni/multivariate polynomials:
}}}
should end in two colons. This is used to generate nice html code.
