XMVectorReciprocalEst function (directxmath.h)
Estimates the per-component reciprocal of a vector.
XMVECTOR XM_CALLCONV XMVectorReciprocalEst( [in] FXMVECTOR V ) noexcept;
Vector whose reciprocal is estimated.
Returns a vector. Each component is an estimate of the reciprocal of the corresponding component of V.
Est functions offer increased performance at the expense of reduced accuracy.
Est functions are appropriate for non-critical calculations where accuracy can be sacrificed for speed.
The exact amount of lost accuracy and speed increase are platform dependent.
Platform RequirementsMicrosoft 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.
