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. ATTRIBUTES
