### impl ModPowerOf2Pow for u64

source§

#### fn mod_power_of_2_pow(self, exp: u64, pow: u64) -> u64

Raises a number to a power modulo another number $2^k$. The base must be already reduced modulo $2^k$.

$f(x, n, k) = y$, where $x, y < 2^k$ and $x^n \equiv y \mod 2^k$.

##### §Worst-case complexity

$T(n) = O(n)$

$M(n) = O(1)$

where $T$ is time, $M$ is additional memory, and $n$ is exp.significant_bits().

##### §Panics

Panics if pow is greater than Self::WIDTH or if self is greater than or equal to $2^k$.
