NAME
     ccosh, ccoshf, csinh, csinhf ctanh, ctanhf -- complex hyperbolic functions

LIBRARY
     Math Library (libm, -lm)

SYNOPSIS
     #include <complex.h>

     double complex
     ccosh(double complex z);

     float complex
     ccoshf(float complex z);

     double complex
     csinh(double complex z);

     float complex
     csinhf(float complex z);

     double complex
     ctanh(double complex z);

     float complex
     ctanhf(float complex z);

DESCRIPTION
     The ccosh(), csinh(), and ctanh() functions compute the hyperbolic cosine, sine, and tangent of the complex number z, respectively.  The
     ccoshf(), csinhf(), and ctanhf() functions perform the same operations in float precision.
