NAME

       ccos, ccosf, ccosl - complex cosine function

SYNOPSIS

       #include <complex.h>

       double complex ccos(double complex z);
       float complex ccosf(float complex z);
       long double complex ccosl(long double complex z);

       Link with -lm.

DESCRIPTION

       These functions calculate the complex cosine of z.

       The complex cosine function is defined as:

           ccos(z) = (exp(i * z) + exp(-i * z)) / 2

VERSIONS

       These functions first appeared in glibc in version 2.1.
