using System;
public class MainClass{
  public static void Main(String[] argv){  
    ulong[] numbers = { UInt64.MinValue, 1234, 123456789, UInt64.MaxValue };
    bool result;
    
    foreach (ulong number in numbers)
    {
       result = Convert.ToBoolean(number);                                 
       Console.WriteLine("{0,-26:N0}  -->  {1}", number, result);
