      public static double clamp(double x, double lower, double upper)
      Returns the value restricted to the given boundaries.

      Parameters:
      x - value to clamp
      lower - lower boundary
      upper - upper boundary
      Returns:
      clamped value

    • normalizeLongitude

      public static double normalizeLongitude(double longitude)
      Returns longitude from range [-180;180) degrees

    • filledArray

      public static double[] filledArray(int length, double value)
      Returns a pre-filled array of primitive Doubles.

      Parameters:
      length - length of the array
      value - value to fill the array with
      Returns:
      new array

    • arrayBinarySearchOps
