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

pub fn wrapping_add<T>(
    lhs: &PrimitiveArray<T>, 
    rhs: &PrimitiveArray<T>
) -> PrimitiveArray<T> where
    T: NativeArithmetics + WrappingAdd<Output = T>, 

This is supported on crate feature compute_arithmetics only.

Wrapping addition of two PrimitiveArrays. It wraps around at the boundary of the type if the result overflows.

Examples

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

let a = PrimitiveArray::from([Some(-100i8), Some(100i8), Some(100i8)]);
let b = PrimitiveArray::from([Some(0i8), Some(100i8), Some(0i8)]);
let result = wrapping_add(&a, &b);
let expected = PrimitiveArray::from([Some(-100i8), Some(-56i8), Some(100i8)]);
assert_eq!(result, expected);
