Answer 2

Well, no VB through VB6 has complex numbers (and vb.net handles it through classes--and I'm not even sure that the net framework has a complex class--memo to self: check). So you're really up against a world of pain. The language doesn't support it natively and creating a class (really a com component) will be very very nasty. VB6 doesn't handle class initialization from constants, for example.

So: if you have the most remote chance of using c++ or fortran, do so. Else, your pain is my pain, but I'm glad it really isn't.

Answer 3

Create your class...
Class ComplexNumber
public realpart as double
public imaginarypart as double

public sub Add(r as double, i as double)
realpart = realpart + r
imaginarypart = imaginarypart + i
end sub

...you get the idea.
