Computes the base e logarithm of each component of a vector. The base e logarithm is also known as the natural logarithm.
- V [in]
Vector for which to compute the base e logarithm.
Returns a vector whose components are base e logarithm of the corresponding components of V.
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.
XMVectorLogE is new for DirectXMath version 3.05. It's similar to the existing XMVectorLog function for Windows 8, but computes base e instead of base 2.
XMVectorLogE is implemented like this:
XMVECTOR Result; Result.x = logf(V.x); Result.y = logf(V.y); Result.z = logf(V.z); Result.w = logf(V.w); return Result;
