CATANH(3M) Mathematical Library Functions CATANH(3M)

NAME

catanh, catanhf, catanhl - complex arc hyperbolic tangent functions

SYNOPSIS

c99 [ flag... ] file... -lm [ library... ]
#include <complex.h>

double complex catanh(double complex z);


float complex catanhf(float complex z);


long double complex catanhl(long double complex z);

DESCRIPTION

These functions compute the complex arc hyperbolic tangent of z, with
branch cuts outside the interval [ -1, +1 ] along the real axis.

RETURN VALUES

These functions return the complex arc hyperbolic tangent value, in
the range of a strip mathematically unbounded along the real axis and
in the interval [ -ipi/2, +ipi/2 ] along the imaginary axis.

ERRORS

No errors are defined.
