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)).
