If this was true, then "infinity" * 0 == 3 would be true, but it is not.
Any number multiplied by 0 is always 0, thus X cannot be a number (as
someone else pointed out, this is probably why IEEE notates it as "NaN").

I'll buy that. :-) Or perhaps rather than undefined, X is the set of all
real numbers (well, complex too).
