Function arrow2::compute::arithmetics::basic::wrapping_negate

pub fn wrapping_negate<T>(array: &PrimitiveArray<T>) -> PrimitiveArray<T> where
    T: NativeType + WrappingNeg, 

Available on crate feature compute_arithmetics only.

Wrapping negates values from array.

Examples

use arrow2::compute::arithmetics::basic::wrapping_negate;
use arrow2::array::{Array, PrimitiveArray};

let a = PrimitiveArray::from([None, Some(6), Some(i8::MIN), Some(7)]);
let result = wrapping_negate(&a);
let expected = PrimitiveArray::from([None, Some(-6), Some(i8::MIN), Some(-7)]);
assert_eq!(result, expected);
