But when the imaginary part is 0 doesn't that mean the number *is* a real?
It seems more intelligent to treat it that way than to mindlessly use complex routines that aren't necessary.

If the case im(z) = 0 is the *only* case that is handled incorrectly, sure. But if the function misbehaves for |im(z)| < ε, only fixing the im(z) = 0 case introduces a discontinuity.
