Complex number in OpenCL

Complex number in OpenCL - cl_complex

Recently I've been involved in the developing of a library OpenCAL capable of  parallel execution of cellular automata  and finite differences models.

I though it could have been fun to render some huge fractal with it and so I ended up writing some OpenCL code for the generation of Julia sets. Unfortunately OpenCL does not provide support for complex number (CUDA does, check the following link out: CUDA complex number example)  so I had to write it myself.

The following might be useful to anyone with need of support for complex number operations as exponentiation, argument, modulus etc. in OpenCL.
