Hi Ganesh, 

That's a good point, i have updated our github documentation as follows:

Please note that the output of the Indio.analogRead() in RAW mode is not of the type INTEGER, but FLOAT. The output range is fixed from 0 to 4096 for all resolutions, but only in 12-bit mode this returns integers; for higher resolution the measurements are floating point numbers.

So you can easily change the resolution setting without having to change your data handling as the range is independent of resolution. Just make sure to use FLOAT type to read your inputs.
