I better fix that then ;p

IronScheme does not support mixed-exactness complex numbers.

From what I recall, make-rectangular deals with some of those cases, which again might need to be revisited for correctness.

I only added support for -0.0 much later and I suspect +/-0.0 was treated as 'exact-zero?'
