  • Add and Subtract 128 Bit Integers in C(++)

    - by Billy ONeal
    Hello :) I'm writing a compressor for a long stream of 128 bit numbers. I would like to store the numbers as differences -- storing only the difference between the numbers rather than the numbers themselves because I can pack the differences in fewer bytes because they are smaller. However, for compression then I need to subtract these 128 bit values, and for decompression I need to add these values. Maximum integer size for my compiler is 64 bits wide. Anyone have any ideas for doing this efficiently? Billy3
