Synopsis
#include <flint/fmpz_lll.h>int fmpz_lll_d(fmpz_mat_t B, fmpz_mat_t U, const fmpz_lll_t fl)sourceint fmpz_lll_d_with_removal(fmpz_mat_t B, fmpz_mat_t U, const fmpz_t gs_B, const fmpz_lll_t fl)sourceL² with Gram–Schmidt data in double precision, the basis vectors being approximated by double vectors scaled by powers of two. Uses the fast Babai procedure (fmpz_lll_check_babai), switching to the heuristic one for one iteration after 50 failures. Fails, returning -1, if the precision is insufficient or an iteration limit is reached.
