_fmpz_vec_get_d_vec_2exp
Synopsis
#include <flint/fmpz_vec.h>Returns an exponent e and sets appv[i] to doubles with appv[i]\cdot 2^e \approx vec[i], where e is the largest exponent of fmpz_get_d_2exp over the entries, so that all appv[i] have absolute value less than 1. Entries much smaller than the largest lose precision or become 0.
