NAME
     ccosh, ccoshf, ccoshl -- complex hyperbolic cosine

SYNOPSIS
     #include <complex.h>

     double complex
     ccosh(double complex z);

     float complex
     ccoshf(float complex z);

     long double complex
     ccoshl(long double complex z);

DESCRIPTION
     The ccosh(), ccoshf() and ccoshl() functions compute the complex
     hyperbolic cosine of z.

     If z = x + iy, then

           ccosh(z) = cosh(x) cos(y) + i sinh(x) sin(y).

RETURN VALUES
     The ccosh(), ccoshf() and ccoshl() functions return the complex
     hyperbolic cosine of z.

SEE ALSO
     csinh(3), ctanh(3)

STANDARDS
     The ccosh(), ccoshf() and ccoshl() functions conform to ISO/IEC 9899:1999
     (``ISO C99'').
