I'm trying to dynamically round data, so values <1000 show the actual number while numbers >1000 are rounded to the thousands. I've found the below linked solution which dynamically rounds and converts them to strings. This works but I'd prefer to leave them as integers instead of converting them to strings so I can use the field with the other measure values and include a grand total.
Are you looking to actually change the numbers or just to format them differently? If you only need to format, then check out the following discussion which deals with that: Custom Number Formatting ($K,$M)
