[−][src]Function directx_math::XMScalarASinEst
pub fn XMScalarASinEst(Value: f32) -> f32
Estimates the arcsine of a floating-point number.
Parameters
Value
float value between -1.0
and 1.0
.
Return value
Returns the inverse sine of Value.
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 3-degree minimax approximation.
