Antoine Pitrou commented on ARROW-16762:
----------------------------------------
Saturated arithmetic would probably use dedicated kernels for performance.
I agree it does not make sense to add them unless there's a real world use case.
> [C++] Implement saturation arithmetic kernels
> ---------------------------------------------

> Key: ARROW-16762
> URL: https://issues.apache.org/jira/browse/ARROW-16762
> Project: Apache Arrow
> Issue Type: New Feature
> Components: C++
> Reporter: Ian Cook
> Priority: Minor
>
> The Arrow C++ library currently lacks saturation arithmetic kernels. I do not
> think it is especially important to add them, but I am curious how
> straightforward it might be. For example could they be implemented by
> extending the {{_checked}} arithmetic kernels to include an option to emit
> the min/max of the type when overflow is detected (in each position of the
> array)?
