.SH NAME
casinh, casinhf, casinhl \- complex arc sine hyperbolic
.SH SYNOPSIS
.B #include <complex.h>
.sp
.BI "double complex casinh(double complex " z ); 
.sp
.BI "float complex casinhf(float complex " z );
.sp
.BI "long double complex casinhl(long double complex " z );

Link with \-lm.
.SH 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].
.LP
One has casinh(z) = clog(z+csqrt(z*z+1)).
