I think you can drop `the` (also applies to the same phrasing
throughout the paragraph)

I'd encourage you to avoid using `:` in this manner.

I am not used to `digits` describing non numeric characters...
This specific section doesn't define `digits`.

This is a definition of digits:

Can it be composed of only two counter symbols that happen to be the same?

I have problems with `an ultimate`, I wouldn't object to `a final`,
the problem is that to me there should be only *one* ultimate, so if
there's more than one, it isn't ultimate, and if there's only one, it
should be `the ultimate`.

is 0 a positive number?

I'd encourage you to move the `[]`s before the `.`, it's really hard
to read this way, I know there's a style for it, but...
