NAME
       acosh(), acoshf(), acoshl(), acoshw(), acoshq() - arc hyperbolic cosine functions

SYNOPSIS
   HP Integrity Server Only
DESCRIPTION
       returns the arc hyperbolic cosine of x, in the range +zero to +INFINITY.

   Integrity Server Only
       is a version of it takes a argument and returns a result.

       is a version of it takes a argument and returns a result.

       is an version of it takes an argument and returns an result.

       is equivalent to on HP-UX systems.

USAGE
       To use (for Integrity servers) compile either with the default option or with the and options.

       To use (for Integrity servers) or compile also with the option.

       To use any of these functions, make sure your program includes and link in the math library by specifying on the compiler or linker command
       line.

       For more information, see the at the following site:

RETURN VALUE
       returns +0.

       If x < 1.0, returns NaN and raises the invalid exception.

       If x is +INFINITY, returns +INFINITY.

       If x is NaN, returns NaN.

       When it raises no other exception, whether raises the inexact exception is unspecified.

ERRORS
       If x < 1.0, sets to [EDOM].

   Integrity Server Only
       HPUX functions on Integrity servers do not set by default.  For setting, compile with the option.
