sincos

sincos, sincosf, sincosl - calculate sin and cos simultaneously

#define _GNU_SOURCE
#include <math.h>
 I void sincos(double  x , double * sin , double * cos );

I void sincosf(float  x , float * sin , float * cos );

I void sincosl(long double  x , long double * sin , long double * cos );

Link with -lm.

Several applications need sine and cosine of the same angle R x . This function computes both at the same time, and stores the results via the given pointers.

This function is a GNU extension.
