Yes, of course, but that's not what I was saying. Since I didn't know
where Peter's use of complex numbers were coming in for his calculation,
I was just offering a way for him to manipulate the real and imaginary
components in double precision separately (It'd be better to avoid the
complex stuff altogether.).
