Description
So the Riemann zeta function has an unsigned infinity.
sage: sig = .01 sage: end = 30 sage: complex_plot(zeta,(0,1),(0.01,end),aspect_ratio=1/end)+line([(sig,0),(sig,end)],linestyle='--') Launched png viewer for Graphics object consisting of 2 graphics primitives sage: complex_plot(zeta,(0,1),(0,end),aspect_ratio=1/end)+line([(sig,0),(sig,end)],linestyle='--') ValueError: unsigned infinity cannot be represented in a float
This should not prevent it from plotting in complex_plot
, especially since it plots fine in one variable at that point (asymptote shows up etc.).

Only partly addressed by #21034.
Doctest in

needs to be updated when fully fixed.
