XMHALF4::XMHALF4(constfloat*) function (directxpackedvector.h)

  • Article

Initializes a new instance of XMHALF4 from a four element float array argument.

This constructor initializes a new instance of XMHALF4 from a four element float array argument.

Note  This constructor is only available under C++.

Syntax

void XMHALF4(
  const float *pArray
) noexcept;

Parameters

pArray

Four element float array containing the values used to initialize the four components of a new instance of XMHALF4.

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 XMHALF4 will be infinity for a 16-bit integer (+0x7FFF).

The following pseudocode demonstrates the operation of this constructor using the XNA Math XMConvertFloatToHalf function:

XMHALF4 instance;

instance.x = XMConvertFloatToHalf(pArray[0]);
instance.y = XMConvertFloatToHalf(pArray[1]);
instance.z = XMConvertFloatToHalf(pArray[2]);
instance.w = XMConvertFloatToHalf(pArray[3]);
