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
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 [-ipi,
No errors are defined.
