CASINH(3) complex math routines CASINH(3)

NAME casinh, casinhf, casinhl - complex arc sine hyperbolic

SYNOPSIS #include <complex.h>

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 = cas- inh(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)).
