[Description]
Floating point tangent.

[Explanation]
tan returns the tangent of floating point argument <I>x</I>, which is assumed
to be specified in radians.
<BR><BR>
<B>Note:</B> tan will return <A HREF="$$LINK(UNSIGNED_INF)">UNSIGNED_INF</A> for all arguments
for which the tangent is infinity. Also, it will return <A HREF="$$LINK(NAN)">NAN</A> if the
argument is so big that reducing to the main period can't be performed without
complete losing of significant digits (i.e. when the magnitude of <I>x</I> is
greater than 1e13).
