When YAP is built using the GNU multiple precision arithmetic library
(GMP), integer arithmetic is unbounded, which means that the size of
integers is only limited by available memory. The type of integer
extern integers is only limited by available memory. The type of integer
support can be detected using the Prolog flags bounded, min_integer
and max_integer. As the use of GMP is default, most of the following
descriptions assume unbounded integer arithmetic.
