Expand description

Divides a number by $2^k$, replacing the number by the remainder. The remainder is non-negative.

If the quotient were computed, the quotient and remainder would satisfy $x = q2^k + r$ and $0 \leq r < 2^k$.

Divides a number by $2^k$, replacing the first number by the remainder.

If the quotient were computed, the quotient and remainder would satisfy $x = q2^k + r$ and $0 \leq r < 2^k$.

$$ x \gets x - 2^k\left \lfloor \frac{x}{2^k} \right \rfloor. $$

Worst-case complexity
