XMVectorReciprocalEst

Estimates the per-component reciprocal of a vector.

Syntax

XMVECTOR XMVectorReciprocalEst(
         XMVECTOR V
)  

Parameters

V
Type: XMVECTOR 

Vector whose reciprocal is estimated.

Return value

Type: XMVECTOR 

Returns a vector. Each component is an estimate of the reciprocal of the corresponding component of V.

Remarks

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.
