    {
        public static double Round3(double number)
        {
            return Math.Round(number, 3);
        }
        public static void Main(String[] args)
        {
            Console.WriteLine("Rounding Math.PI = " + Round3(Math.PI));

            double number = 1.45674;
            Console.WriteLine("Rounding number = " + Round3(number));
