void _fmpz_mod_vec_get_fmpz_vec_smod(fmpz * res, const fmpz * vec, slong len, const fmpz_mod_ctx_t ctx)source

Given canonical residues (vec,len)(\mathit{vec}, \mathit{len}), sets (res,len)(\mathit{res}, \mathit{len}) to the symmetric residues in (−n/2,n/2](-n/2, n/2]. This is the same as _fmpz_vec_scalar_smod_fmpz but faster, since the input is known to be reduced: each entry costs one comparison and at most one subtraction.
