        {
            double d = 123.21;
            Console.WriteLine(Math.Round(d, 1, MidpointRounding.AwayFromZero));

            d = 123.321;
            Console.WriteLine(Math.Round(d, 1, MidpointRounding.AwayFromZero));

            d = 123.45;
            Console.WriteLine(Math.Round(d, 1, MidpointRounding.AwayFromZero));

            d = 123.74;
            Console.WriteLine(Math.Round(d, 1, MidpointRounding.AwayFromZero));

            d = 123.75;
            Console.WriteLine(Math.Round(d, 1, MidpointRounding.AwayFromZero));

            d = 123.76;
            Console.WriteLine(Math.Round(d, 1, MidpointRounding.AwayFromZero));
        }
    }
