Comment (by behackl):
Coincidentally, this solves my original problem. However, I still think
that the fact that this
{{{
sage: zetaderiv(1, CIF(-600)).n()
}}}
is both very slow and raises the `NoConvergence`-error is a problem.
Is it possible to use a numerically more stable version of the derivative
of the zeta function? Maybe someone knowing more about this numerical
stuff could help with this.
