ccoshl (3) - Linux Manuals

ccoshl: complex hyperbolic cosine

Command to display ccoshl manual in Linux: $ man 3 ccoshl

NAME

ccosh, ccoshf, ccoshl - complex hyperbolic cosine

SYNOPSIS

#include <complex.h>

double complex ccosh(double complex z);
float complex ccoshf(float complex z);
long double complex ccoshl(long double complex z);

Link with -lm.

DESCRIPTION

These functions calculate the complex hyperbolic cosine of z.

The complex hyperbolic cosine function is defined as:

    ccosh(z) = (exp(z)+exp(-z))/2

VERSIONS

These functions first appeared in glibc in version 2.1.
