      • Range

        public Range​(double lower,
             double upper)
        Constructs a new Range.
        Parameters:
        lower - Lower bound. Must be positive or zero
        upper - Upper bound
        Throws:
        java.lang.IllegalArgumentException - if the range is invalid (lower < 0 || lower >= upper)

    • Method Detail

      • contains

        public boolean contains​(double x)
        Check if a number is contained in this range
        Parameters:
        x - The number to test
        Returns:
        true if it is in this range

      • cut

        public static Range cut​(Range a,
                        Range b)
        provides the intersection of 2 overlapping ranges
        Parameters:
        a - first range
        b - second range
        Returns:
        intersection of a and b

      • reduceAround

        public Range reduceAround​(double x,
