XMStoreUDecN4 method

Stores an XMVECTOR in an XMUDECN4.

Syntax


VOID XMStoreUDecN4(
  [out]  XMUDECN4 *pDestination,
  [in]   XMVECTOR V
);

Parameters

pDestination [out]

Address at which to store the data.

V [in]

Vector containing the data to store.

Return value

None.

Remarks

The following pseudocode demonstrates the operation of the function.


XMVECTOR N;	
static const XMVECTOR  Scale = {1023.0f, 1023.0f, 1023.0f, 3.0f};

assert(pDestination);

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

pDestination->v = ((uint32_t)N.v[3] << 30) |
                  (((uint32_t)N.v[2] & 0x3FF) << 20) |
                  (((uint32_t)N.v[1] & 0x3FF) << 10) |
                  (((uint32_t)N.v[0] & 0x3FF));
