void _mp_real_tan_sc(nn_ptr y, ulong * err, nn_srcptr v, slong n)source

Set (y, n + 1) to \tan v for v \in [0, 1) and n \le 32 from the sine and cosine kernels and one division (64-bit only). With both kernel outputs within E ulps, err is \lfloor 19E/4 \rfloor + 2. The tangent kernel uses it up to 22 limbs.
