XMHALF2::XMHALF2(float,float) function (directxpackedvector.h)

  • Article

Initializes a new instance of XMHALF2 from two float arguments.

This constructor initializes a new instance of XMHALF2 from two float arguments.

Note  This constructor is only available under C++.
 

Syntax

void XMHALF2(
  float _x,
  float _y
) noexcept;

Parameters

_x

Value of the x-coordinate of the vector, the x member of the new XMHALF2 instance.

_y

Value of the y-coordinate of the vector, the y member of the new XMHALF2 instance.

Return value

None

Remarks

If the magnitude of one of this constructor's floating point arguments 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(_x);
	instance.y = XMConvertFloatToHalf(_y);
