For better accuracy, i have used external shunts and low voltage input (that ohm one). Then i have those measured amperes in (milli-)volts and have to calculate with some crazy factor what it really means.

“Free math channels” could address this, so i’ll vote for that instead of just moving decimal points with software, without any other improvements. But, if we get to use maths in our apps, just moving decimal point would be the easiest thing to do.
