--------------------------------
Assignee: Yibo Cai
> [C++] Improve precision range error messages for Decimal128Type/Decimal256Type
> ------------------------------------------------------------------------------
>
> Key: ARROW-14842
> URL: https://issues.apache.org/jira/browse/ARROW-14842
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C, R
> Reporter: Dragoș Moldovan-Grünfeld
> Assignee: Yibo Cai
> Priority: Major
>
> The error message surfaces in R like so:
> {code:r}
> decimal(0, 2)
> Error: Invalid: Decimal precision out of range: 0
> {code}
> and
> {code:r}
> decimal(100, 2)
> Error: Invalid: Decimal precision out of range: 100
> {code}
>
> Could we improve the error message to be a bit more informative? As it is it
> doesn't specify what the range should be (1 to 38 for Decimal128Type, for
> example).
