RE: Solving sqrt(i)=z, one or two solutions?
@sasa:
A student does not expect two answers when running sqrt(), independently of the type of the argument. sqrt(4.0) return 2.0 (approx), sqrt(4) returns 2 in a CAS. Returning two values would confuse them, how can you argue the contrary?
BTW, Wolfram Alpha returns one value for sqrt(i) :-)

As for complex analysis support inside Giac: some integrals are computed using the residue method, and there is a residue command.

Reading all these attacks from sasa, I wonder why... Perhaps students are beginning to buy Primes instead of using Mathematica or Wolfram Alpha :-)

Ok, I think I've lost enough time in this thread, bye!
