+INDEX
+        casinhf
+
+SYNOPSIS
+       #include <complex.h>
+       double complex casinh(double complex <[z]>);
+       float complex casinhf(float complex <[z]>);
+
+
+DESCRIPTION
+        @ifnottex
+        These functions compute the complex arc hyperbolic sine of <[z]>,
+        with branch cuts outside the interval [-i, +i] along the 
+        imaginary axis.        
+        @end ifnottex
+        @tex
+        These functions compute the complex arc hyperbolic sine of <[z]>,
+        with branch cuts outside the interval [$-i$, $+i$] along the 
+        imaginary axis.        
+        @end tex
+
+        <<casinhf>> is identical to <<casinh>>, except that it performs
+        its calculations on <<floats complex>>.
+
+RETURNS
+        @ifnottex
+        These functions return the complex arc hyperbolic sine value, 
+        in the range of a strip mathematically unbounded along the 
+        real axis and in the interval [-i*p/2, +i*p/2] along the 
+        imaginary axis.
+        @end ifnottex
+        @tex
+        These functions return the complex arc hyperbolic sine value, 
+        in the range of a strip mathematically unbounded along the 
+        real axis and in the interval [$-i\pi/2$, $+i\pi/2$] along the 
+        imaginary axis.
+        @end tex
