Okay, my HugeFloat class is working very well doing all standard mathematical operations (+ - / * %) (and fast; Pi to 10,000 digits squared took only about 12 seconds). Anyway I would like to implement binary operations (^ | & ~) but am thinking it may be more of a challenge than I bargained for. My data is stored with two digits of the true value in each element of a byte array. So for example, 1234 would be stored something like:  = 34,  = 12. I think that no matter how the separated data are stored it would be a tricky task to try anything that inherently relies on the bits being arranged in a particular order.
Do you have any bright ideas about how one might go about performing binary arithmetic given this situation? Any thoughts are appreciated. Cam on.
