To round the digits after the decimal point, we can use String.Format() method, here is the example.

using System;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            //Only two decimal points
            Console.WriteLine("Two digits after decimal point");
            Console.WriteLine(String.Format("{0:0.00}", 512.4246));     
            Console.WriteLine(String.Format("{0:0.00}", 512.4));        
            Console.WriteLine(String.Format("{0:0.00}", 512.0));

            Console.WriteLine("\n\nThree digits after decimal point");
            Console.WriteLine(String.Format("{0:0.000}", 512.4246));
            Console.WriteLine(String.Format("{0:0.000}", 512.4));
            Console.WriteLine(String.Format("{0:0.000}", 512.0));

            Console.WriteLine();  
        }
    }
}

Output

512.42
512.40
