			// Byte to float conversion will not overflow.
			floatVal = System.Convert.ToSingle(byteVal);
			System.Console.WriteLine("The byte as a float is {0}.",
				floatVal);

			// Float to byte conversion can overflow. 
			try {
				byteVal = System.Convert.ToByte(floatVal);
				System.Console.WriteLine("The float as a byte is {0}.",
					byteVal);
			}
