Address at which to store the data.

V [in]

Remarks

The following pseudocode demonstrates the operation of the function.


XMVECTOR N;	
static const XMVECTOR  Scale = {511.0f, 511.0f, 511.0f, 1.0f};

N = XMVectorClamp(V, g_XMNegativeOne, g_XMOne);
N = XMVectorMultiply(N, Scale);

pDestination->v = ((int32_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));
