ca_is_qq_elem, ca_is_qq_elem_zero, ca_is_qq_elem_one, ca_is_qq_elem_integer
Synopsis
#include <flint/ca.h>Returns whether x is represented as an element of \mathbb{Q}, as the element 0 or 1 of \mathbb{Q}, or as an integer in \mathbb{Q}. Since operations normally demote rational results to \mathbb{Q} (see ca_condense_field), a rational value usually has this representation, but this is not guaranteed.
