NAME
casinh, casinhf, casinhl - complex arc sine hyperbolicSYNOPSIS
#include <complex.h>DESCRIPTION
The casinh() function calculates 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))
VERSIONS
These functions first appeared in glibc in version 2.1.CONFORMING TO
