// The example displays the following output: 
//       Converted the UInt64 value 0 to the Byte value 0. 
//       Converted the UInt64 value 121 to the Byte value 121. 
//       The UInt64 value 340 is outside the range of the Byte type. 
//       The UInt64 value 18446744073709551615 is outside the range of the Byte type.
