NAME
       ctanh(), ctanhf(), ctanhl(), ctanhw(), ctanhq() - complex hyperbolic tangent functions

SYNOPSIS
DESCRIPTION
       These functions are available only for Integrity servers.

       returns the complex hyperbolic tangent of z.

       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+i0.

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

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

       returns for positive-signed finite y.
