Function num_traits::pow::pow
source · [−]pub fn pow<T: Clone + One + Mul<T, Output = T>>(base: T, exp: usize) -> T
Expand description
Raises a value to the power of exp, using exponentiation by squaring.
Note that 0⁰
(pow(0, 0)
) returns 1
. Mathematically this is undefined.
Example
use num_traits::pow;
assert_eq!(pow(2i8, 4), 16);
assert_eq!(pow(6u8, 3), 216);
assert_eq!(pow(0u8, 0), 1); // Be aware if this case affects you
