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

Link with -lm.

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,pi/2].

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