NAME
       cacosh(), cacoshf(), cacoshl(), cacoshw(), cacoshq() - complex arc hyperbolic cosine functions

SYNOPSIS
DESCRIPTION
       These functions are available only for Integrity servers.

       returns the complex arc hyperbolic cosine of z, 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.  There is a branch cut at values less than 1 along the real axis.

       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 these functions, compile with the default option.  To use compile with the option.  Make sure your program includes Link in the math
       library by specifying on the compiler or linker command line.

RETURN VALUE
       =

       returns +0+iPi/2.

       returns +Inf+iPi/2, for finite x.

       returns NaN+iNaN and optionally raises the invalid floating-point exception, for finite x.

       returns +Inf+iPi, for positive-signed finite y.

       returns +Inf+i0, for positive-signed finite y.

       returns +Inf+i3Pi/4.

       returns +Inf+iPi/4.

       returns +Inf+iNaN.

       returns NaN+iNaN and optionally raises the invalid floating-point exception, for finite y.

       returns +Inf+iNaN.

       returns NaN+iNaN.
