The following primitives are provided for verifying whether a term is
a big int, creating a term from a big integer and to access the value
of a big int from a term.

YAP must support bignum for the configuration you are using (check
the YAP configuration and setup). For now, Yap only supports the GNU
GMP library and the @code{MP_INT *} type.
Currently, no primitives are supplied to users for manipulating data base
references.
