XMStoreHalf4

Stores an XMVECTOR in an XMHALF4.

Syntax

void XMStoreHalf4(
         XMHALF4 *pDestination,
         XMVECTOR V
)  

Parameters

pDestination
Type: XMHALF4 *

[out]

Address at which to store the data.

V
Type: XMVECTOR 

[in]

Vector containing the data to store.

Return value

None.

Remarks

This function takes a vector, converts the components into a half-precision format, and writes the results out to four half-precision floating-point values at the given address. The most significant component is written to the first two bytes of the address, the next most significant component is written to the next two bytes of the address, and so on.

The following pseudocode demonstrates the operation of the function.

pDestination->x = XMConvertFloatToHalf(V.x); // 2 bytes to address pDestination
pDestination->y = XMConvertFloatToHalf(V.y); // 2 bytes to address (uint8_t*)pDestination + 2
pDestination->z = XMConvertFloatToHalf(V.z); // 2 bytes to address (uint8_t*)pDestination + 4
pDestination->w = XMConvertFloatToHalf(V.w); // 2 bytes to address (uint8_t*)pDestination + 6
