cacosh(3M) Mathematical Library Functions cacosh(3M)NAME
cacosh, cacoshf, cacoshl - complex arc hyperbolic cosine functions
SYNOPSIS
c99 [ flag... ] file... -lm [ library... ]
#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 compute the complex arc hyperbolic cosine of z, with a
branch cut at values less than 1 along the real axis.
RETURN VALUES
These functions 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, +ipi ] along the imaginary axis.
ERRORS
No errors are defined.
