    • nonNegativeAbs

      public static int nonNegativeAbs(int a)
      Returns the closest non-negative int value to the absolute value of a. Works the same way as Math.abs(int) for all values except Integer.MIN_VALUE, for which Math.abs(int) returns negative value but this method returns Integer.MAX_VALUE.

      Use this method instead of the standard one if it's important to get non-negative result and Integer.MIN_VALUE may be passed as an argument (e.g. if the argument is a result of Object.hashCode() or Random.nextInt() call).

    • clamp

      public static int clamp(int value, int min, int max)
      Clamps the value to fit between min and max
      Parameters:
      value - value to clamp
      min - min allowed value
      max - max allowed value
      Returns:
      a clamped value that fits into [min..max] interval
      Throws:
      IllegalArgumentException - if min > max

    • clamp

      public static long clamp(long value, long min, long max)
      Clamps the value to fit between min and max
      Parameters:
      value - value to clamp
      min - min allowed value
      max - max allowed value
      Returns:
      a clamped value that fits into [min..max] interval
      Throws:
      IllegalArgumentException - if min > max

    • clamp

      public static double clamp(double value, double min, double max)
      Clamps the value to fit between min and max
      Parameters:
      value - value to clamp
      min - min allowed value
      max - max allowed value
      Returns:
      a clamped value that fits into [min..max] interval
      Throws:
