Function polars::export::arrow::compute::arithmetics::basic::negate

pub fn negate<T>(array: &PrimitiveArray<T>) -> PrimitiveArray<T> where
    T: NativeType + Neg<Output = T>, 

This is supported on crate feature compute_arithmetics only.

Negates values from array.

Examples

use arrow2::compute::arithmetics::basic::negate;
use arrow2::array::PrimitiveArray;

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