it is not binary that makes discrete, you think if you choose decimal will make things better? no way. That fact is: integer, rational number, algebraic numbers and computable transcendental number are all discrete, the cardinal of all these sets are exactly the same, aleph null the cardinal number of the set of integer, and they are all discrete.
