Regardless, a discrete representation is the only kind of
representation
possible with digital computers. You play the cards you're dealt.
For myself, I would really like it if an exact representation of pi was possible. But outside of a computer algebra system, it isn't.

If you have a finite domain, you can put the elements in order. The
order
can exist and be well-defined, independent of whether it "makes sense."
