The rval and lrvl fields are declared  as DBF_LONG in motorRecord.dbd.

In opposite to what is explained in documentation/motorRecord.html,

Does it make sense to turn them into double ?
This would ease the usage of servo motors and/or controllers
that talk engineering units on the line.

And at the same time, add the "set point dead band" ?

What are the pros and cons for long vs double ?
