Trait typenum::type_operators::Pow [−][src]
A type operator that provides exponentiation by repeated squaring.
Example
use typenum::{Integer, Pow, N3, P3}; assert_eq!(<N3 as Pow<P3>>::Output::to_i32(), -27);

fn powi(self, exp: Exp) -> Self::Output
[src]
This function isn’t used in this crate, but may be useful for others. It is implemented for primitives.
Example
use typenum::{Pow, U3}; let a = 7u32.powi(U3::new()); let b = 7u32.pow(3); assert_eq!(a, b); let x = 3.0.powi(U3::new()); let y = 27.0; assert_eq!(x, y);
