# XMVector2AngleBetweenVectors function


## -description


Computes the radian angle between two 2D vectors.


## -parameters




### -param V1 [in]

2D vector.


### -param V2 [in]

2D vector.


## -returns



Returns a vector. The radian angle between <i>V1</i> and <i>V2</i> is replicated to each of the components.




## -remarks



If V1 and V2 are normalized 2D vectors, it is faster to use <a href="https://docs.microsoft.com/windows/desktop/api/directxmath/nf-directxmath-xmvector2anglebetweennormals">XMVector2AngleBetweenNormals</a>.

<h3><a id="Platform_Requirements"></a><a id="platform_requirements"></a><a id="PLATFORM_REQUIREMENTS"></a>Platform Requirements</h3>
Microsoft Visual Studio 2010 or Microsoft Visual Studio 2012 with the Windows SDK for Windows 8. Supported for Win32 desktop apps, Windows Store apps, and Windows Phone 8 apps.
