gr_ctx_init_real_arb, gr_ctx_init_complex_acb
Synopsis
#include <flint/gr.h>Initialise ctx to the field of real or complex numbers represented by balls of type arb_struct and acb_struct, computing with a working precision of prec bits. The precision can be changed with gr_ctx_set_real_prec. Every result is an enclosure of the exact result; predicates return T_UNKNOWN when the balls do not decide them.
