[controlP5] best way to make setDecimalPrecision effect value, not just display
setDecimalPrecision does not change actual value - http://www.sojamo.com/libraries/controlP5/reference/controlP5/Controller.html#setDecimalPrecision(int).
what is the best way to do this automatically (i.e. not just rounding after the fact)? example:
cp5.addSlider("someNumber")
.setRange(0.5, 5.0)
.setDecimalPrecision(1);
// a displayed value of 3.4 might actually be 3.42
(ideally there would be two different methods: setDecimalPrecision and setDisplayedDecimalPrecision)
