CACOSH(3P)              POSIX Programmer's Manual             CACOSH(3P)

PROLOG

       This manual page is part of the POSIX Programmer's Manual.  The
       Linux implementation of this interface may differ (consult the
       corresponding Linux manual page for details of Linux behavior),
       or the interface may not be implemented on Linux.

NAME

       cacosh, cacoshf, cacoshl — complex arc hyperbolic cosine
       functions

SYNOPSIS

       #include <complex.h>

       double complex cacosh(double complex z);
       float complex cacoshf(float complex z);
       long double complex cacoshl(long double complex z);

DESCRIPTION

       The functionality described on this reference page is aligned
       with the ISO C standard. Any conflict between the requirements
       described here and the ISO C standard is unintentional. This
       volume of POSIX.1‐2017 defers to the ISO C standard.

       These functions shall compute the complex arc hyperbolic cosine
       of z, with a branch cut at values less than 1 along the real
       axis.

RETURN VALUE

       These functions shall return the complex arc hyperbolic cosine
       value, in the range of a half-strip of non-negative values along
       the real axis and in the interval [-iπ, +iπ] along the imaginary
       axis.
