**I don't think that's what he's getting at - real numbers ***are* complex.

Complex in this context means a number with a non-zero imaginary component, methinks.

I don't know if that includes numbers that are purely imaginary or not.

For the uninitiated, in its broadest sense, a complex number is any number of the form a + b*i, where a and b are any real number, and i is the square root of -1, a number that does not exist within the realm of real numbers.

a is call the real part and b*i the imaginary part.
