NAME

casinh, casinhf, casinhl − complex arc sine hyperbolic

SYNOPSIS

#include

double complex casinh(double complex z);
float complex casinhf(float complex z);
long double complex casinhl(long double complex z);

Link with −lm.

DESCRIPTION

These functions calculate the complex arc hyperbolic sine of z. If y = casinh(z), then z = csinh(y). The imaginary part of y is chosen in the interval [−pi/2,pi/2].

One has:

casinh(z) = clog(z + csqrt(z bodies manpages.csv script_extrae_body.sh script.sh usr z + 1))

VERSIONS

These functions first appeared in glibc in version 2.1.
