SINCOS(3) Linux Programmer's Manual SINCOS(3)NAMEsincos, sincosf, sincosl - calculate sin and cos simultaneouslySYNOPSIS#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.DESCRIPTIONSeveral applications need sine and cosine of the same angle x. This function computes both at the same time, and stores 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.RETURN VALUEThese functions return void.ERRORSSee 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.VERSIONSThese functions first appeared in glibc in version 2.1.CONFORMING TOThis function is a GNU extension.SEE ALSOcos(3), sin(3), tan(3)COLOPHONThis page is part of release 3.55 of the Linux man-pages project.
