    Command:

    cacoshf

    
    
    

    SYNOPSIS

           #include <complex.h>
    
           double complex cacosh(double complex z);
           float complex cacoshf(float complex z);
           long double complex cacoshl(long double complex z);
    
           Link with -lm.
    
    
    

    DESCRIPTION

           The  cacosh()  function calculates the complex arc hyperbolic cosine of
           z.  If y = cacosh(z), then z = ccosh(y).  The imaginary part  of  y  is
           chosen in the interval [-pi,pi].  The real part of y is chosen nonnega-
           tive.
    
           One has:
    
               cacosh(z) = 2 * clog(csqrt((z + 1) / 2) + csqrt((z - 1) / 2))
    
    
    

    VERSIONS

           These functions first appeared in glibc in version 2.1.

    EXAMPLE

           /* Link with "-lm" */
    
           #include <complex.h>
           #include <stdlib.h>
           #include <unistd.h>
           #include <stdio.h>
    
           int
           main(int argc, char *argv[])
           {
               double complex z, c, f;
    
               if (argc != 3) {
                   fprintf(stderr, "Usage: %s <real> <imag>\n", argv[0]);
                   exit(EXIT_FAILURE);
               }
    
               z = atof(argv[1]) + atof(argv[2]) * I;
    
               c = cacosh(z);
               printf("cacosh() = %6.3f %6.3f*i\n", creal(c), cimag(c));
    
               f = 2 * clog(csqrt((z + 1)/2) + csqrt((z - 1)/2));
               printf("formula  = %6.3f %6.3f*i\n", creal(f2), cimag(f2));
    
               exit(EXIT_SUCCESS);
