But in Ada you could just use a type similar to this:

type degree is mod 360;

theta : degree := 0;

to achieve the same nice wrap around effect with less convulated code.

It's one of the things I really like about Ada: you can generally
achieve the semantics you want easily with a little bit of knowledge.
