void _nmod_vec_nored_ll_scalar_addmul_halflimb(nn_ptr res, nn_srcptr vec, slong len, ulong c)source

void _nmod_vec_nored_ll_scalar_addmul(nn_ptr res, nn_srcptr vec, slong len, ulong c)source

Sets $r_i \gets r_i + c \, v_i$ for $0 \le i < \mathit{len}$ without reduction, where $v_i$ is vec[i] and $r_i$ is the two-limb integer stored least significant limb first at res + 2 i. Requires $r_i + c v_i < 2^{2 \mathtt{FLINT\_BITS}}$ . The _halflimb version also requires $c v_i < 2^{\mathtt{FLINT\_BITS}}$ .
