CACOSH(3)                  Library Functions Manual                  CACOSH(3)

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 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 [-i pi, +i pi] along the imaginary axis.

ERRORS
     No errors are defined.
