Subject: Dealing with Granularity in Output Records

We have a situation where analog output records have a built in granularity. If a user attempts to change the value using his/her favorite EPICS program (probe, edm, etc.), The value that actually is sent to the device may be slightly different from the value typed into the program interface due to the granularity of the underlying device.

Here's the question. What is the normal practice for display programs such as an edm screen? Do they show the value entered regardless of the actual value that is sent or should the interface show an adjusted value based on the nearest acceptable value after granularity has been accounted?
