XMVectorLogE function (directxmath.h)
Computes the base e logarithm of each component of a vector.The base e logarithm is also known as the natural logarithm.
XMVECTOR XM_CALLCONV XMVectorLogE( [in] FXMVECTOR V ) noexcept;
Vector for which to compute the base e logarithm.
Returns a vector whose components are base e logarithm of the corresponding components of V.
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;
