XMStoreXDecN4 function

-description

Stores an XMVECTOR in an XMXDECN4.

-parameters

-param pDestination [out]

Address at which to store the data.

-param V [in]

Vector containing the data to store.

-returns

None.

-remarks

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));

Platform Requirements

Microsoft Visual Studio 2010 or Microsoft Visual Studio 2012 with the Windows SDK for Windows 8. Supported for Win32 desktop apps, Windows Store apps, and Windows Phone 8 apps.
