Thank you Kris,

I'll consider the integer case as well. I believe it would be
a separate library.

The set of real numbers in the range [l,h) with the defined circular
operation + is indeed a bounded group (z is the identity element, and -c is
the inverse element of c) - according to the definitions in sections 14,16
of the article.

However, all other defined operations (multiplication/division with real
numbers, trigonometric functions, etc.) extend circular value mathematics
beyond the scope of group algebra.

Lior.
