I thought I'd take a crack at implementing a math system that can deal with (very simple) equations and solve for unknowns. While I was thinking of ways this may be accomplished, I began to wonder... just how can I deal with really huge numbers? What if I need to store a number with 1000 digits, for example? How is this done? I know it can be done; I've seen plenty of software do it before. Is there a way to create a C++ class to represent such an enourmous value? Also, would it be possible to use templates to indicate the type of the huge number? (So HugeNumber<Decimal> would store huge floating point values and HugeNumber<Integer> would store huge integer values.) Thanks! I'm really curious about this one.
