Synopsis
#include <flint/fmpz.h>fmpz_preinvn_structfmpz_preinvn_tA precomputed inverse of a divisor h for fmpz_fdiv_qr_preinvn: the fields are dinv (an n-limb approximation of the reciprocal of h', computed by flint_mpn_preinvn, where h' is |h| shifted left by norm bits to have its top bit set) and n (the number of limbs of h).
