CATANH(3)                  Linux Programmer's Manual                 CATANH(3)

NAME
       catanh, catanhf, catanhl - complex arc tangents hyperbolic

SYNOPSIS
       #include <complex.h>

       double complex catanh(double complex z);
       float complex catanhf(float complex z);
       long double complex catanhl(long double complex z);

       Link with -lm.

DESCRIPTION
       The  catanh() function calculates the complex arc hyperbolic tangent of
       z.  If y = catanh(z), then z = ctanh(y).  The imaginary part  of  y  is
       chosen in the interval [-pi/2,pi/2].

       One has:

           catanh(z) = 0.5 * clog((1 + z) / (1 - z))

VERSIONS
       These functions first appeared in glibc in version 2.1.

CONFORMING TO
       C99.
