gr_ctx_init_real_qqbar, gr_ctx_init_complex_qqbar
Synopsis
#include <flint/gr.h>Initialise ctx to the field of real algebraic numbers \overline{\mathbb{Q}} \cap \mathbb{R}, respectively all algebraic numbers \overline{\mathbb{Q}}, with elements of type qqbar_struct (a minimal polynomial and an isolating ball; see qqbar and the guide to qqbar). Arithmetic is exact and equality is decidable, but the degree of results can grow quickly.
