If you don't need provably correct answers then just work over CDF or ComplexField with a precision that you'd like.
If you want to prove something you can use CIF (floating-point complex interval arithmetic) or QQbar (exact numbers). The difference between pure mathematics and applications is just a choice of goal, not a choice of tools. On Saturday, June 14, 2014 6:03:47 PM UTC+1, [email protected] wrote: > > Thanks.
