    Description

      This is reproducible when running without simd features, or when trying to compile on an aarch64 machine as well.

       

      % cargo test --no-default-features

       

      failures:---- compute::kernels::arithmetic::tests::test_primitive_array_divide_with_nulls stdout ----
      thread 'compute::kernels::arithmetic::tests::test_primitive_array_divide_with_nulls' panicked at 'called `Result::unwrap()` on an `Err` value: DivideByZero', src/libcore/result.rs:1187:5
      failures:
          compute::kernels::arithmetic::tests::test_primitive_array_divide_with_nullstest result: FAILED. 312 passed; 1 failed; 0 ignored; 0 measured; 0 filtered out 

       

      I tried to address the issue this myself, and it looks like the divide function with the simd feature doesn't work properly, something is up with math_op but I don't understand this well enough.
