__sincos(3) [osx man page]
__SINCOS(3) BSD Library Functions Manual __SINCOS(3) NAME
__sincos -- sine-cosine function SYNOPSIS
#include <math.h> void __sincosf(float x, float *sinp, float *cosp); void __sincos(double x, double *sinp, double *cosp); DESCRIPTION
The __sincos() function computes the sine and cosine of x (measured in radians) and stores the sine in the memory pointed to by sinp and the cosine in the memory pointed to by cosp. SPECIAL VALUES
__sincos(+-0, sinp, cosp) sets *sinp to +-0 and sets *cosp to +1. __sincos(+-infinity, sinp, cosp) raises the "invalid" floating-point exception and sets both *sinp and *cosp to NaN. VECTOR OPERATIONS
If you need to apply the __sincos() function to SIMD vectors or arrays, using the following functions provided by the Accelerate.framework may be useful: #include <Accelerate/Accelerate.h> vFloat vsincosf(vFloat x, vFloat *c); void vvsincosf(float *s, float *c, const float *x, const int *n); void vvsincos(double *s, double *c, const double *x, const int *n); SEE ALSO
