NAME
     cacosh, cacoshf, cacoshl -  complex  arc  hyperbolic  cosine
     functions

SYNOPSIS
     c99 [ flag... ] file... -lm [ library... ]
     #include 

     double complex cacosh(double complex z);


     float complex cacoshf(float complex z);


     long double complex cacoshl(long double complex z);


DESCRIPTION
     These functions compute the complex arc hyperbolic cosine of
     z,  with  a  branch cut at values less than 1 along the real
     axis.

RETURN VALUES
     These functions return the  complex  arc  hyperbolic  cosine
     value,  in  the range of a half-strip of non-negative values
     along the real axis and in the interval [ -ipi, ]ipi ] along
     the imaginary axis.

ERORS
     No errors are defined.
