XMHALF2::XMHALF2(constfloat*) function (directxpackedvector.h)
Initializes a new instance of XMHALF2 from a two element float array argument.
This constructor initializes a new instance of** XMHALF2** from a two element float array argument.
Note This constructor is only available under C++.
Syntax
void XMHALF2(
const float *pArray
) noexcept;
Parameters
pArray
Two element float array containing the values used to initialize the two components of a new instance of XMHALF2.
Return value
None
Remarks
If the magnitude of one of the members of pArray cannot be represented by the HALF type, the corresponding member of the new instance of XMHALF2 will be infinity for a 16-bit integer (+0x7FFF).
The following pseudocode demonstrates the operation of this constructor using the XNA Math XMConvertFloatToHalf function:
XMHALF2 instance;
instance.x = XMConvertFloatToHalf(pArray[0]);
instance.y = XMConvertFloatToHalf(pArray[1]);
