I cannot accept that there is no such thing as a non-negative
*complex* number. A complex number has a (possibly zero but
usually not) real number element which is sufficient to displace
it off the zero line in the complex plane. Most numbers in the
complex plane are either to the right of the zero line (positive)
or to its left (negative), regardless of the value of their
imaginary co-ordinate."

I give up.

However any such characteristic is not innate to the complex
number. All you have to do is rotate the coordintes and you can
alter the sign of the real portion. I maintain you can assign
signs (and relative magnitudes) to either the real or imaginary
components, provided you specify the coordinate system. Anything
further is just foolish.
