[Description]
Complex hyperbolic cosine.

[Explanation]
ccosh calculates the hyperbolic cosine w&nbsp;=&nbsp;cosh(z) of the complex number which real and
imaginary parts are <I>z_re</I> and <I>z_im</I>, and stores real and
imaginary part of the result in floating point destinations pointed to by
<I>w_re</I> and <I>w_im</I>. The complex hyperbolic cosine is defined by
<BR><BR>
cosh(z)&nbsp;=&nbsp;(exp(z)&nbsp;+&nbsp;exp(-z))&nbsp;/&nbsp;2
<BR><BR>
where <B>exp</B> is complex exponential function
(see <A HREF="$$LINK(cexp)">cexp</A>).
