Replaces a number with its absolute value, saturating at the numeric bounds instead of overflowing.

$$ x \gets \begin{cases} |x| & \text{if} \quad x > -2^{W-1}, \\ 2^{W-1} - 1 & \text{if} \quad x = -2^{W-1}, \end{cases} $$ where $W$ is Self::WIDTH.

Worst-case complexity

Constant time and additional memory.
