Main point is that it ism, i think it is a nice way express very big numbers without any approximation.
Another is that we can encode any number making a square modular number system doing mathematic in, since it seem consistent enough doing arithmetic in, without go back to standard bases. So it is not just naturals it work perfectly good for reals.
Another point i do not which to spell out i rather implement it and refine it before showing. But that point is probably the reason i implemented it in the first case, but i think this encoding of numbersystem is quite useful.
