Title: Cast Aggregation
Post by: RBPLC on October 30, 2020, 08:30:44 PM

I'm trying to aggregate two Unsigned Words (say V10 and V11). I type V10:R into the Data Window and press Enter. The Data Window changes this to V10:RD. Why the RD instead of R? From the help menu I would expect this to be R. Am I missing something? The aggregation works as expected, I'm just confused as to why it automatically changes to RD.

B, W, and D are sizes. R, S, and U are formats. When you specify R for a bit, byte, or word it implies a size change, which gets shown. If you used R on a double type (like D data type), the size doesn't change and we don't show the size modifier.
