Hello all!

I was trying to evaluate the Riemann Zeta function.

Both in home and CAS it works when the imaginary part is an integer, I can evaluate Zeta(0.5+14i).

When the imaginary part is not an integer I become an answer containing the Eta function, I have found no way to have an approximate (real+imaginary) result. So for Zeta(0.5+14.1i) I can not find any usable evaluation.

How should I do it?

Thank you very much
