Ternary

This is already the case with binary representation, though. You can't represent 1/3 as a finite decimal point expression in base 2. Come to think of it, that's true of decimal as well. There will always be numbers without a finite representation.

It really comes down to which numbers you like the most. Personally I like 1/7, but fuck base 7, I'm sticking with powers of 2
