[−][src]Function directx_math::XMVectorCosEst
pub fn XMVectorCosEst(V: FXMVECTOR) -> XMVECTOR
Estimates the cosine of each component of an XMVECTOR.
Parameters
V Vector for which to compute the cosine.
Return value
Returns a vector. Each component is an estimate of the cosine 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.
This function uses a 7-degree minimax approximation.
