XMScalarSinEst function (directxmath.h)
Estimates the sine of a radian angle.
Syntax
float XMScalarSinEst(
[in] float Value
) noexcept;
Parameters
[in] Value
float value describing the radian angle.
Return value
Returns an estimate of the 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 7-degree minimax approximation.
Platform Requirements
Microsoft 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.Requirements
