NAME
casinh, casinhf, casinhl - complex arc sine hyperbolic
LIBRARY
Math library
( libm,~ -lm)
SYNOPSIS
#include <complex.h>
double complex casinh(double complex z);
float complex casinhf(float complex z);
long double complex casinhl(long double complex z);
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 * z + 1))
