> [Gandiva] Add overflow checks for decimals
> ------------------------------------------
>
> Key: ARROW-4570
> URL: https://issues.apache.org/jira/browse/ARROW-4570
> Project: Apache Arrow
> Issue Type: Bug
> Components: C++ - Gandiva
> Reporter: Pindikura Ravindra
> Priority: Major
>
> For decimals, overflows can occur at two places :
> # input array can have values that are outside the bound (eg. > 38 digits)
> # When an operation can result in overflows. eg. add of two decimals of (38,
> 6) can result in an overflow, if the input numbers are very large.
> In both the above cases, just verifying that an overflow occurred can be a
> perf overhead. We should do this based on a conf variable.
