Yes, because the definition of a natural number is satisfied for any finite number of digits. It isn't, however, satisfied when the number of digits isn't finite, which was the case in the example I gave. Quote:

No, you simply made that up, and it's clearly incorrect, as each natural number is also a real number. Even if I ignored that error, asserting that my example is a real number wouldn't justify asserting that it's a specific natural number.
