Select the number of decimal places that should be visible on screen. The
number will be rounded down if the selected number of places will not fit on the
screen. If 'Auto' is selected, then any trailing '0' digits will be
truncated from the display.
In "Frac" mode, the precision list will show fractions, such as "1/2" or
"1/64", instead of decimal places.
