         intVal = System::Convert::ToInt32( doubleVal );
         System::Console::WriteLine( " {0} as an int is: {1}",
         doubleVal, intVal );
      }

      {
         System::Console::WriteLine( "Overflow in double-to-int conversion." );
      }

      // Int to double conversion cannot overflow.
      doubleVal = System::Convert::ToDouble( intVal );
