    I'm not exactly sure I understand the problem... Perhaps you could explain how you "embed" things in the int.

    If I was looking for the maximum of ten things and needed to decide between equal values, one way would be to choose the last of the equal values. Or the first. (Or, possibly, I could do the embedding with *all* of the maximum values if I thought equal values would not be very common.)

    But then there is a little problem with decoding. It might be that the "embedding" operation changes the int value so that it is no longer the maximum. It seems to me that this could be a problem whatever scheme you choose to decide the int to embed into. Which is why it might help to provide more details.

    Not sure I understand the question. Can you post the code you're trying with the error?

    Just realized this was a duplicate post. Please don't post multiple threads on the same topic in different areas of the forum.
