Synopsis
#include <flint/qqbar.h>void _qqbar_enclosure_raw(acb_t res, const fmpz_poly_t poly, const acb_t z, slong prec)sourceSets res to an enclosure of the root of poly isolated by z (or of x) with about prec bits of accuracy, by interval Newton steps with doubling precision; if a step fails to improve the accuracy enough, the roots are recomputed from scratch at higher precision. If z is already accurate enough, it is returned without rounding. The result is not polished as by qqbar_get_acb.
