[−]
[src]
pub fn pow<T: Clone + One + Mul<T, Output=T>>(base: T, exp: usize) -> T
Raises a value to the power of exp, using exponentiation by squaring.
Example
extern crate num; fn main() { use num; assert_eq!(num::pow(2i8, 4), 16); assert_eq!(num::pow(6u8, 3), 216); }use num; assert_eq!(num::pow(2i8, 4), 16); assert_eq!(num::pow(6u8, 3), 216);
