Some implementers wanted restrictions to ease very optimized
implementations, especually when it come to copying. It is a rather dumb
restriction. I use complex<int> but wouldn't try <complex<X> for a type X
with a copy constructor.
Another reason is: some of the mathematical operations are not meaningful if
you can't
represent a fractional value.
