And don't forget complex numbers or higher dimensionality.

The complex numbers and quaternions are still represented using floating point numbers.

Yeah, I'm aware, but you need to accurately compute abs/magnitude, which presents its own complexities. Including exponentials, it's highly related to the non-trivial accurate computation of trigonometric functions of floats.
