    Use if statements maybe? I can smell an assignment lurking around!

    Why do you need to?

    You could just use an unsigned short array, and then ignore the extra range if you don't need it.

    Or create a templated Array class?

    There are various ways to implement so-called "discriminated unions", and the Variant library from Boost is an excellent implementation. But I agree with dwks - I really don't think you need a union here.

    i think template should be feasible as it will save memory space for me....
