Thank you for filing this feedback item. We will evaluate this for the next major release of SQL Server.Glenn Berry commented
This functionality has been asked for multiple times in the past, with no success. The most recent rejection was because of the fact that many previously EE-only programmability features were added to SQL Server 2016 Standard Edition SP1, which made this functionality unnecessary. This ignores the fact that there are still some EE-only features and performance differences between SE and EE. There are also license limits for things like sockets, cores, and memory in Standard Edition.
So, we ended up with:
1) Limit the number to 2 (two) decimal digits
2) Format the number using the “thousand separator” (e.g. 1,234.5 [ENU[ or 1.234,5 [ITA], etc…
The change will be visible in the next version of SSMS.
