XMBYTE2::XMBYTE2(constfloat*) function (directxpackedvector.h)
Initializes a new instance of XMBYTE2 from a two-element float array argument.
This constructor initializes a new instance of XMBYTE2 from a two-element float array argument.
Note This constructor is only available with C++.
Syntax
void XMBYTE2(
const float *pArray
) noexcept;
Parameters
pArray
Two-element float array containing the values used to initialize the two components of a new instance of XMBYTE2.
Return value
None
Remarks
The magnitude of each member of the pArray argument to the constructor will be clamped to the range supported by an 8-bit signed integer [-127.0, 127.0].
The following pseudocode demonstrates the operation of this constructor:
XMBYTE2 instance;
instance.x = (int8_t)min( max( pArray[0] -127.0 ), 127.0 );
instance.y = (int8_t)min( max( pArray[1] -127.0 ), 127.0 );
