Calculate with ulong

using System;
    class MainClass
    {
        static void Main(string[] args)
        {
            ulong loopCount = 0;
            ulong factorial = 1;
            loopCount = 23;
            for( ulong i = loopCount; i > 0; i-- )
            {
                factorial *= i;
            }
            Console.WriteLine( "{0}! = {1}", loopCount, factorial );
        }
    }

Dividing a Float by Zero, Displaying NaN

class MainClass
{
  static void Main()
  {
    float n=0f;
    System.Console.WriteLine(n / 0);
  }
}

Overflowing the Bounds of a float

class MainClass
{
  static void Main()
  {
    System.Console.WriteLine(-1f / 0);
    System.Console.WriteLine(3.402823E+38f * 2f);
  }
}

Use long to compute the distance from the Earth to the sun in inches

using System; 
 
class MainClass {    
  public static void Main() {    
    long inches; 
    long miles; 
   
    miles = 93000000; // 93,000,000 miles to the sun 
 
    // 5,280 feet in a mile, 12 inches in a foot 
    inches = miles * 5280 * 12; 
   
    Console.WriteLine("Distance to the sun: " + inches + " inches."); 
   
  }    
}

Distance to the sun: 5892480000000 inches.
