            double A = 2;
            double B = 3;
            double C = A/B;
            double D = Math.Round(A / B, 2);//精度到小數點第二位,第三位四捨五入
            Console.WriteLine(“2/3={0}”, 1/3);//整數運算
            Console.WriteLine(“2/3={0}”, C);//標準浮點數
            Console.WriteLine(“2/3={0}”, D);//四捨五入浮點數
            Console.WriteLine(“2/3={0}”, C.ToString(“0.00”));//數字轉字串方法
