                                    long denominator)
        Converts a fraction into a percentage
        Parameters:
        numerator - numerator
        denominator - denominator
        Returns:
        the calculated percentage

      • normalize

        public static double normalize​(double current,
                               double minimum,
                               double maximum)
        Normalizes a given value to a value between 0.00 and 1.00
        Parameters:
        current - The current value
        minimum - The minimum value
        maximum - The maximum value
        Returns:
        A normalized value

      • round

        public static double round​(double number,
                           int significantPlaces)
        Rounds a double to a specified amount of significant digits. If the number is infinite or NaN, then it's returned unmodified.

      • rate

        public static double rate​(java.util.concurrent.TimeUnit unit,
                          long runtime,
                          double value)
        Parameters:
        unit - the time unit
        runtime - the runtime in milliseconds
        value - the value to calculate the rate of
        Returns:
        the amount of value collected during runtime at the rate of unit

      • getDistanceBetweenAngles
