XMVectorLog2 function (directxmath.h)
Computes the base two logarithm of each component of a vector.
Syntax
XMVECTOR XM_CALLCONV XMVectorLog2(
[in] FXMVECTOR V
) noexcept;
Parameters
[in] V
Vector for which to compute the base two logarithm.
Return value
Returns a vector whose components are base two logarithm of the corresponding components of V.
Remarks
Platform Requirements
Microsoft Visual Studio 2010 or Microsoft Visual Studio 2012 with the Windows SDK for Windows 8.1. Supported for Win32 desktop apps, Windows Store apps, and Windows Phone 8 apps.XMVectorLog2 is new for DirectXMath version 3.05, but it's just a renamed version of the existing XMVectorLog function for Windows 8.
XMVectorLog2 is implemented like this:
XMVECTOR Result;
Result.x = log2f(V.x);
Result.y = log2f(V.y);
Result.z = log2f(V.z);
Result.w = log2f(V.w);
return Result;
