XMVectorRotateLeft method

Rotates the vector left by a given number of 32-bit elements.

Syntax


XMVECTOR XMVectorRotateLeft(
  [in]  XMVECTOR V,
  [in]  uint32_t Elements
);

Parameters

V [in]

Vector to rotate left.

Elements [in]

Number of 32-bit elements by which to rotate V left. This parameter must be 0, 1, 2, or 3.

Return value

Returns the rotated XMVECTOR.

Remarks

The following code demonstrates how this function may be used.


XMVECTOR v = XMVectorSet( 10.0f, 20.0f, 30.0f, 40.0f );
XMVECTOR result = XMVectorRotateLeft( v, 1 );

The rotated vector (result) will be <20.0f, 30.0f, 40.0f, 10.0f>.

In the case of a constant rotate value, it is more efficient to use the template form of XMVectorRotateLeft:



template<uint32_t Elements>
    XMVECTOR XMVectorRotateLeft(FXMVECTOR V)
   

Platform Requirements
