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 );
