Estimates both the sine and cosine of a radian angle.
- pSin [out]
Address of a float that will contain the result of the sine of Value.
- pCos [out]
Address of a float that will contain the result of the cosine of Value.
- Value [in]
float value describing the radian angle.
This function does not return a value.
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 for sine; 6-degree for cosine.
