Is the fix as simple as adding the word "floor" before "division" in the "equivalent to division by [...]" phrase?
> A right shift by n bits is equivalent to floor division by pow(2, n) without overflow check.
This text was probably written before // was introduced; maybe we can rewrite in terms of //? "x >> n" should be identical to "x // pow(2, n)" for any nonnegative "n".
I confess that I've no idea what the "without overflow check" bit means, but I suspect it's no longer relevant post int/long-unification.
