The precision specifier controls the number of significant digits or zeros to the right of a decimal:

   
  
using System;

public class FormatSpecApp {
    public static void Main(string[] args) {
        int i = 123456;
        
        Console.WriteLine("{0:C5}", i);
        Console.WriteLine("{0:D5}", i);
        Console.WriteLine("{0:E5}", i);
        Console.WriteLine("{0:F5}", i);
        Console.WriteLine("{0:G5}", i);
        Console.WriteLine("{0:N5}", i);
        Console.WriteLine("{0:P5}", i);
        Console.WriteLine("{0:X5}", i);
    }
}

   
     


int array property

   
  

using System;

public class SomeClass
{
    private int[] nums;
    public SomeClass(int i)
    {
        nums = new int[10];
        nums[0] = i;
    }
    public int[] Nums
    {
        get { return nums; }
        set { nums = value; }
    }
}
   
public class MainClass
{
    public static void Main(string[] args)
    {
        SomeClass sc = new SomeClass(42);
        Console.WriteLine("{0}", sc.Nums[0]);
   
        sc.Nums[0] = sc.Nums[0] + 5;
        Console.WriteLine("{0}", sc.Nums[0]);
    }
}

   
     


Use #, % and in int format

   
  

using System;
public class FormatSpecApp {
    public static void Main(string[] args) {
        int i = 123456;
        Console.WriteLine();
        Console.WriteLine("{0:#0}", i);             // 123456
        Console.WriteLine("{0:#0;(#0)}", i);        // 123456
        Console.WriteLine("{0:#0;(#0);<zero>}", i); // 123456
        Console.WriteLine("{0:#%}", i);     // 12345600%

        i = -123456;
        Console.WriteLine();
        Console.WriteLine("{0:#0}", i);             // -123456
        Console.WriteLine("{0:#0;(#0)}", i);        // (123456)
        Console.WriteLine("{0:#0;(#0);<zero>}", i); // (123456)
        Console.WriteLine("{0:#%}", i);             // -12345600%

        i = 0;
        Console.WriteLine();
        Console.WriteLine("{0:#0}", i);             // 0
        Console.WriteLine("{0:#0;(#0)}", i);        // 0
        Console.WriteLine("{0:#0;(#0);<zero>}", i); // <zero>
        Console.WriteLine("{0:#%}", i);             // %
    }
