The functionality provided through this property is that of a gauge which only measures in distinct increments. This reduces ambiguity in reading the gauge, and also prevents the marker from "twitching" when the input value is changing rapidly in very small increments.
For example, if a gauge is set to display the CPU usage every 100 milliseconds (WinGauge), the marker will appear to shake rapidly around one value when the computer is idle. Set the Precision property to .5 so changes of less than .5 will not be displayed.
More examples: If this property is set to .5, a Value of 23.3 will be rounded to 23.5. If this property is set to 2.0, a Value of 23.3 will be rounded to 24.0.
