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.
