Thanks very much for the recent update, zeta() seems
to be a lot faster now. I'd like to ask someone to check
one value which may be producing a bad evaluation.

Under pari Version 2.0.17 (beta)
? zeta(4.45+292532.0*I)
%4 = 0.9628325946986762532107312785 - 0.007964269348872060270684500688*I 

Under pari Version 2.2.7 (alpha)
(13:13) gp > zeta(4.45+292532.0*I)
%77 = -1.519052693065775291998804237 E84 + 3.820179262621090164984728018 
E84*I

Which (if any) of these is correct?


FWIW, Mathematica and 2.0.17 are in agreement:
    0.962833 - 0.00796427*I
