sincos, sincosf, sincosl - calculate sin and cos simultaneously


   #define _GNU_SOURCE         /* See feature_test_macros(7) */
   #include <math.h>

   void sincos(double x, double *sin, double *cos);
   void sincosf(float x, float *sin, float *cos);
   void sincosl(long double x, long double *sin, long double *cos);

   Link with -lm.


   Several  applications  need sine and cosine of the same angle x.  These
   functions compute both at the same time, and store the results in  *sin
   and *cos.

   If x is a NaN, a NaN is returned in *sin and *cos.

   If  x is positive infinity or negative infinity, a domain error occurs,
   and a NaN is returned in *sin and *cos.


   These functions return void.


   See math_error(7) for information on how to determine whether an  error
   has occurred when calling these functions.

   The following errors can occur:

   Domain error: x is an infinity
          An invalid floating-point exception (FE_INVALID) is raised.

   These functions do not set errno.


   These functions first appeared in glibc in version 2.1.
