radix_divrem_preinv
Synopsis
#include <flint/radix.h>void radix_divrem_preinv(nn_ptr q, nn_ptr r, nn_srcptr a, slong an, nn_srcptr b, slong bn, nn_srcptr binv, slong binvn, const radix_t radix)sourceradix_divrem with a precomputed inverse of b given as (\mathit{binv}, \mathit{binvn} + 2) with \mathit{binvn} fraction limbs, as computed by radix_inv_approx. Requires \mathit{binvn} \ge \mathit{an} - \mathit{bn} + 1; a few extra limbs can improve performance. r may be NULL.
