[GitHub] [arrow-datafusion] mingmwang commented on pull request #5675: Decimal multiply kernel should not cause precision loss

mingmwang commented on PR #5675:
URL: https://github.com/apache/arrow-datafusion/pull/5675#issuecomment-1500212176

   Does this new  `PromotePrecision` expr only apply to Decimal type?  
   I remember in the SparkSQL there was a similar `PromotePrecision`, not sure whether it is for the same purpose.
   And looks like in the latest Spark, it is removed or renamed.
