CASINH(3)

NAME
casinh, casinhf, casinhl - complex arc sine hyperbolic

SYNOPSIS
#include <complex.h>

double complex casinh(double complex z);

float complex casinhf(float complex double z);

long double complex casinhl(long double complex z);

DESCRIPTION
The casinh() function calculates the complex asinh(). If y = casinh(z), then z = csinh(y). The imaginary part of y is chosen in the interval [-pi/2*i,pi/2*i].

One has casinh(z) = clog(z+csqrt(z*z+1)).
