Function lowhalf¶
function lowhalf(const vec<T, N> &) simd¶
template <typename T, size_t N, size_t Nout = N / 2>
KFR_INTRINSIC vec<T, Nout> lowhalf(const vec<T, N>& x)Extracts the lower half of x.
| T | Element type of the vector. |
| N | Input vector length. |
| Nout | Output length, defaults to N / 2. |
| x | Source vector. |
A vector holding the first Nout elements of x. |
