Re: Improved Complex number string representation

[Krux02]

@smitty, that has nothing to do with string representation. The complex numbers 
are internally nothing more than two numbers. So even though the type is 
different, it should be safe to simply cast from `Complex` to `array[2, 
float]`. But honestly, I just looked it up, I couldn't find any Complex32 or 
Complex64 type. I think, that would clearly be worth invenstigating.
