-------------------------+-----------------------------
The type of return value of some functions (`polylog`, `zeta`) is
inconsistent:
{{{
sage: zeta(1)
Infinity
sage: zeta(1.)
+infinity
sage: polylog(1,1)
Infinity
sage: polylog(1.,1.)
+infinity
sage: type(_)
<type 'sage.rings.real_mpfr.RealNumber'>
}}}
