NAME
__sincospi —
sine-pi and cosine-pi
function
SYNOPSIS
#include
<math.h>
void
__sincospif(float
x, float *sinp,
float *cosp);
void
__sincospi(double
x, double *sinp,
double *cosp);
DESCRIPTION
The
__sincospi()
function computes the sine and cosine of pi times 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
__sincospi() produces the same results as
separate calls to
__sinpi()
and
__cospi().
