You don't need a 64bit machine to use 64bit ints but you do need to use
a recent C/C++ standard, long long was introduced in C99 and C++11. That
is, if you have an issue with long long add -std=c++11 to your CXXFLAGS.

There is also a long double

Try it -

#include <stdio.h>

int main()
{
    printf("sizeof long long - %lu\n",sizeof(long long));
    printf("sizeof long double - %lu\n",sizeof(long double));
    return 0;
}
