[GitHub] [arrow-datafusion] Dandandan commented on issue #5143: Decimal multiplication / addition are lossy

   That might be part of the problem / why this issue bubbles up (the one implementing it at least).
   I don't think it would be strictly necessary to keep this property, as the datatype is dynamic.
   
   We should probably have to change some type calculation (`get_type` etc.) in DataFusion to correctly give the outcome types though given the decimal operations.
