Function arrow2::compute::arithmetics::basic::checked_powf_scalar

pub fn checked_powf_scalar<T>(
    array: &PrimitiveArray<T>,
    exponent: usize
) -> PrimitiveArray<T> where
    T: NativeArithmetics + CheckedMul + One, 

Available on crate feature compute_arithmetics only.

Checked operation of raising an array of primitives to the power of exponent. If the result from the multiplications overflows, the validity for that index is changed returned.

Examples

use arrow2::compute::arithmetics::basic::checked_powf_scalar;
use arrow2::array::Int8Array;

let a = Int8Array::from(&[Some(1i8), None, Some(7i8)]);
let actual = checked_powf_scalar(&a, 8usize);
let expected = Int8Array::from(&[Some(1i8), None, None]);
assert_eq!(expected, actual);
