+
+These functions are only available if C<isl> has been compiled with C<GMP>
+support.
+
+Specific integer and rational values can be created from C<GMP> values using
+the following functions.
+
+ #include <isl/val_gmp.h>
+ __isl_give isl_val *isl_val_int_from_gmp(isl_ctx *ctx,
+ mpz_t z);
+ __isl_give isl_val *isl_val_from_gmp(isl_ctx *ctx,
+ const mpz_t n, const mpz_t d);
+
+The numerator and denominator of a rational value can be extracted as
+C<GMP> values using the following functions.
+
+ #include <isl/val_gmp.h>
+ int isl_val_get_num_gmp(__isl_keep isl_val *v, mpz_t z);

+=head2 Multiple Values
+
+An C<isl_multi_val> object represents a sequence of zero or more values,
+living in a set space.
+
+An C<isl_multi_val> can be constructed from an C<isl_val_list>
+using the following function
+
+ #include <isl/val.h>
+ __isl_give isl_multi_val *isl_multi_val_from_val_list(
+ __isl_take isl_space *space,
+ __isl_take isl_val_list *list);

+The zero multiple value (with value zero for each set dimension)
+can be created using the following function.
+
+ #include <isl/val.h>
+ __isl_give isl_multi_val *isl_multi_val_zero(
+ __isl_take isl_space *space);
