Function arrow2::compute::arithmetics::basic::overflowing_add

pub fn overflowing_add<T>(
    lhs: &PrimitiveArray<T>,
    rhs: &PrimitiveArray<T>
) -> (PrimitiveArray<T>, Bitmap) where
    T: NativeArithmetics + OverflowingAdd<Output = T>, 

Available on crate feature compute_arithmetics only.

Overflowing addition of two primitive arrays. If the result from the sum is larger than the possible number for this type, the result for the operation will be an array with overflowed values and a validity array indicating the overflowing elements from the array.

Examples

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

let a = PrimitiveArray::from([Some(1i8), Some(100i8)]);
let b = PrimitiveArray::from([Some(1i8), Some(100i8)]);
let (result, overflow) = overflowing_add(&a, &b);
let expected = PrimitiveArray::from([Some(2i8), Some(-56i8)]);
assert_eq!(result, expected);
