Just an unrelated advice:
Avoid use of complex with mixed exactness (ie. the real part is exact and the
imaginary part is inexact, or the opposite) : it is almost always better to do
pz(.5+10000.0*I) or pz(1/2+10000*I)
rather than
pz(.5+10000*I) or pz(1/2+10000.0*I)
because exact and inexact types have different semantics in PARI, and mixing
types lead to mixed semantics which are hard to predict.

Cheers,
Bill.
