Fist: I do not throw away zero. I merely say there is no actually
accessible real "number" zero but scores of doubles instead. So I do not
have to bother about the possibility to simply separate the reals in
positive ans negative one with nothing, in other words with -0.0 oberbar
  = +0.0 overbar in between.

Second: Our decimal system uses integers including zero as to
approximate reals.

Third: Removal of a finite number of real "numbers" from Q or R does not
harm the continuum at all. In order to get a deficite, one would have to
remove infinitely much.
