    data type long enough to store 2^64

    I can't seem to find a data type that can store integers up to length 2^64. Can anyone point me in the right direction?

    Edit:

    Unsigned long long int works, but it seems to not be working with the modulus on other unsigned long long ints.

    Probably depends on which compiler you are using. In gcc 3.4.5, it works fine to do x % y where x and/or y is a long long.

    Compilers can produce warnings - make the compiler programmers happy: Use them!
    Please don't PM me for help - and no, I don't do help over instant messengers.
