NAME
       catanh(), catanhf(), catanhl(), catanhw(), catanhq() - complex arc hyperbolic tangent functions

SYNOPSIS
DESCRIPTION
       These functions are available only for Integrity servers.

       returns	the  complex arc hyperbolic tangent of z, in the range of a strip mathematically unbounded along the real axis and in the interval
       along the imaginary axis.  Branch cuts are outside the interval [-1,+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
       = and is odd.

       returns +0+i0.

       returns +0+iNaN.

       returns +Inf+i0 and raises the divide-by-zero floating-point exception.

       returns for finite positive-signed x.

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

       returns for finite positive-signed y.

       returns

       returns +0+iNaN.

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

       returns (where the sign of the real part of the result is unspecified).

       returns NaN+iNaN.

ERRORS
       No errors are defined.
