XMSHORT2::XMSHORT2(constfloat*) function (directxpackedvector.h)
Initializes a new instance of XMSHORT2 from a two element float array argument.
This constructor initializes a new instance of XMSHORT2 from a two element float array argument.
Note This constructor is only available under C++.
Syntax
void XMSHORT2(
const float *pArray
) noexcept;
Parameters
pArray
Two element float array containing the values used to initialize the two components of a new instance of XMSHORT2.
Return value
None
Remarks
The magnitude of each member of the pArray argument to the constructor will be clamped to the range supported by a 16-bit signed integer [-32767.0, 32767.0].
The following pseudocode demonstrates the operation of this constructor:
XMSHORT2 instance;
instance.x = (int16_t)min( max( pArray[0] -32767.0 ), 32767.0 );
instance.y = (int16_t)min( max( pArray[1] -32767.0 ), 32767.0 );
