void XM_CALLCONV XMStoreUDec4(
[out] XMUDEC4 *pDestination,
[in] FXMVECTOR V
) noexcept;
Parameters
[out] pDestination
Address at which to store the data.
[in] V
Vector containing the data to store.
Return value
None.
Remarks
The following pseudocode demonstrates the operation of the function.
XMVECTOR N;
static const XMVECTOR Max = {1023.0f, 1023.0f, 1023.0f, 3.0f};
assert(pDestination);
N = XMVectorClamp(V, XMVectorZero(), Max);
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));
