I remember seeing this somewhere, but for the life of me, I can't seem to find it again.
I have some values, in my case, battery voltage and the amp draw from my motors. To keep the resolution, but loose the float, things get multiplied by 10. For example, my voltage within the program would be considered 117. When I display this value on my screen, I want to see 11.7 volts. I need to artificially add that decimal point --only so I, a human, can read it more easily.
