sincos(3) |
sincos − calculate sin and cos simultaneously
#include <math.h>
double sincos(double x, double *sin, double *cos);
float sincosf(float x, float *sin, float *cos);
long double sincosl(long double x, long double *sin, long double *cos);
Several applications need sine and cosine of the same angle x. This function computes both at the same time, and stores the results via the given pointers.
This function is a GNU extension.
