You can't do all that if angles are just numbers.
I think that the discussion of percentages is relevant here: angles //are// just numbers, but you're choosing a particular way of displaying them (or reading them). 100% //is// 1, and 360° //is// 2π. So really, like, for instance, number base, they're things that exist for I/O but not inside the system. At least for the purposes of doing maths: computer type systems often don't have very much to do with maths (for instance floating-point numbers are obviously a very important type, but don't map onto anything that would be interesting to a theoratical physicist).
