Subject: changing unit string to scale factor
I have a device which returns a value and a string indicating the units of the value. I’ll get inputs like 0.3nA or 3.4mA, etc. Since I want to report the value in a consistent unit, I want to convert the unit string to a scale factor (nA=1, uA=1000, mA=10000) and then use a calc record to scale the value. CALC records seem to only take numbers as input and I don’t see any other appropriate record type.
In programming I would use a case statement or if-elseif constructs. How do I do this with EPICS record processing?
