The easiest is to use `long long unsigned' for all variables to have 64-bit variables. That too, however, has its limit. For larger value, use a library such as https://gmplib.org/ Aside from that, this question is off-topic for this mailing list, which deals with questions specific to GCC. You can try the mailing list of gmplib.org instead. -- Best regards, Tadeus
