Trait malachite_base::num::arithmetic::traits::NegModPowerOf2Assign
source · pub trait NegModPowerOf2Assign {
// Required method
fn neg_mod_power_of_2_assign(&mut self, other: u64);
}
Expand description
Divides the negative of a number by $2^k$, replacing the number by the remainder.
If the quotient were computed, the quotient and remainder would satisfy $x = q2^k - r$ and $0 \leq r < 2^k$.

source§fn neg_mod_power_of_2_assign(&mut self, pow: u64)
fn neg_mod_power_of_2_assign(&mut self, pow: u64)
Divides the negative of a number by $2^k$, returning just the remainder.
If the quotient were computed, the quotient and remainder would satisfy $x = q2^k - r$ and $0 \leq r < 2^k$.
$$ x \gets 2^k\left \lceil \frac{x}{2^k} \right \rceil - x. $$
