Sqrt of -1

Is this possible in VB?
I know how to work with complex numbers (adding, subtraction, division, multiply) in borland c++, but in vb?

You have to represent complex numbers with a UDT like

Code:

---

Type Complex
        r as Single
        imag as Single
End Type
Dim Im as Complex

---

Then you have to do all the math in functions that you write yourself.

Code:

---

Function ComplexAdd(a as Complex,b as Complex) as Complex
    Dim tmp as Complex
    tmp.r = a.r + b.r
    tmp.imag = a.imag + b.imag
    ComplexAdd = tmp
End Function

---

thnx men, it look alot like C++. I thought it was more difficult then that! :p
