NAME
catanh, catanhf, catanhl - complex arc tangents hyperbolicSYNOPSIS
#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 atanh(). 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)).
