# [−] [src] Function num_traits::pow::pow

    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.

Note that `0⁰` (`pow(0, 0)`) returnes `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

## Search Tricks

Prefix searches with a type followed by a colon (e.g., `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g., `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
