    big integer

    hi!
    does any one have a prewritten class for handling really big integers(100 digits....).
    Just basic operations
    Its really helpful in coding contests, like java has the inbuilt BigInteger class.

    thanx in advance.
    Cheers!

    Ps: please paste the code,as I am not able to download anything.

    I'm pretty sure that any pre-written class to do this would be slightly larger than what we would want to have posted here.

    A member with the user-name iMalc has a big integer class, which if you would like to download it, is here: http://homepages.ihug.co.nz/~aurora7...ul_Classes.htm

    More than just basic operations, but also in all likelyhood considerably faster than anything any individual member here has produced.

    LGPL, though. Be aware of the conditions.
    All the buzzt!
