Hi Craig,
Rev does not need to be able to get the square root of -1 (or any
negative number) to be able to do computations with Complex numbers.
A complex number consists of a real part and an imaginary part :
E.g. 3 + 2i where 'i' is the unit for the imaginary part. Now I can
easily add another complex number to this one : (3 + 2i) + (7 - 8i) =
10 - 6i. The real parts are added and the imaginary parts are added.
Same goes for subtraction. Also multiplication and division are
simple. Powers and higher roots are a bit more tricky and I guess
logs etc as well. I have made a start with a library, but was
thinking if someone has done this before, it would free some of my
time for the things I want to use the lib for. I use the complex
numbers to make transformations in the complex plane and Rieman
sphere (Fractals, Möbius transformations etc.).
By the way, dividing by 0 in the realm complex numbers results to
infinity. (That's what I always suspected in high school, but the
teacher wouldn't budge).
Vice versa, if there is anyone who wants to have what I have up till
now as library for this, I am glad to share. In the meantime, I still
hope someone has made a library before me.
Cheers,
Beat
