    Algorithm for sbyte?

    Dear All,

    Does anyone know the algorithm used to convert to an sbyte like follows? It
    is not a straight hex conversion.

    sbyte.Parse("B2 ", System.Globaliz ation.NumberSty les.HexNumber, null);

    Any help is appreciated. Thanks and have a great day!

    Cheers,
    Rich

      It is a straight hex conversion and ends up storing the same binary value in
      the byte as it would in an unsigned byte. Its how the binary value is then
      interpreted as a number. The top bit being set indicates its a negative
      number in signed byte.

      The algorithm is called 2's complement. See:-
