By definition if something does not measure what the dimension actually says it is sloppy and incorrect.
If the dimension is correct then you will not need to round it off and in AC and most CAD programs not using the correct information takes more time and effort than doing it correctly. In the extreme cases that you need to override the actual dimension then you would mark it in yellow and add approx. to it so that everyone is aware that it is different.
In my office if somebody does what you are suggesting I would fire them if it is done on purpose after one warning.

But I might not see what your special use case is.
That being the case I have one project were I had to lower the dim setting to not have fractional inches and now I am fixing all those rounded off dimensions because professionally I don't want to have to tell the client that I didn't do the job properly.
