Since computed items are new data items, confirm or change the data type of the item to preserve the precision of a mixed-data type computations, or to change the way a data item is handled (for example, interpreting number as strings). This ensures the correct handling of data in server computations.
Attention to data types is most important when computing items in the Query section. Here the computation is performed on the database server, and the computed item may be handled with an unanticipated data type.
Local calculations (Results or Pivot) are handled internally, and adjustment between 16- and 32-bit integers can be handled safely using the automatic or number data type specification.
