Are you asking if a user process can do math with 64-bit integers?
Read 'man printf' a bit more carefully:

     o   The optional character q, specifying that a following d, i, o, u, x,
         or X conversion corresponds to a quad int or unsigned quad int argu-
         ment, or that a following n conversion corresponds to a pointer to a
         quad int argument.

/*
  showLongLong.c
  */
#include <stdio.h>
main() {
  long long x;
  x = -2;
  printf("%d %qd %16qx\n",sizeof(x),x,x);
}
