casinhl(3) -- Linux man page
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)).
