It is called modular arithmetic.  So not just idiomatic, but expected.

Is there really anyone who has learned to code who doesn't understand
that an N-bit register does math modulus 2^N?  Or how twos-complement
math works?

(There may be some these days unfamiliar with ones-complement, but
unfamiliarity with unsigned modular arithmetic and twos-complement
signed modular arithmetic seems to contradict an understanding of
how current computers work.  And understanding how a given chip works
seems prerequisite to understanding how to code for it.)
