using System;  
   public static class MyMath  
       public static float PI=3.14f;   
       public static int cube(int n){return n*n*n;}  
   class TestMyMath{  
       public static void Main(string[] args)  
            Console.WriteLine("Value of PI is: "+MyMath.PI);  
            Console.WriteLine("Cube of 3 is: " + MyMath.cube(3));  

C# examples - Output :

Value of PI is: 3.14
Cube of 3 is: 27
