Synopsis
#include <flint/fmpz_lll.h>void fmpz_lll_packed_tighten(fmpz_lll_packed_t P, slong i)sourcevoid fmpz_lll_packed_grow(fmpz_lll_packed_t P)sourcevoid fmpz_lll_packed_maybe_shrink(fmpz_lll_packed_t P)sourceRecomputes the exact bit bound of row i; increases the number of limbs per entry by one; decreases it by one if all rows fit comfortably in one limb less.
