And yet if you take the real numbers modulo a constant, and use the
addition operator [rather than the multiplicative operator used on
complex numbers with a norm of 1, which seems to be the usual example
used to describe U(1)] - you have U(1) all over again.

More exactly, a group isomorphic to U(1). It probably has a name, but
I couldn't find it with Google.
