Stores an XMVECTOR in an XMXDECN4.
void XMStoreXDecN4(
XMXDECN4 *pDestination,
XMVECTOR V
)
pDestination
Type: XMXDECN4 *
[out]
Address at which to store the data.
V
Type: XMVECTOR
[in]
Vector containing the data to store.
The following pseudocode demonstrates the operation of the function.
XMVECTOR N;
static const XMVECTOR Min = {-1.0f, -1.0f, -1.0f, 0.0f};
static const XMVECTOR Scale = {511.0f, 511.0f, 511.0f, 3.0f};
assert(pDestination);
N = XMVectorClamp(V, Min, g_XMOne);
N = XMVectorMultiply(N, Scale);
N = XMVectorRound(N);
pDestination->v = ((uint32_t)N.v[3] << 30) |
(((int32_t)N.v[2] & 0x3FF) << 20) |
(((int32_t)N.v[1] & 0x3FF) << 10) |
(((int32_t)N.v[0] & 0x3FF));
