5. Platform-dependent packages
</h1>
Certain facilities have been developed for use on Unix-like platforms,
which is currently the main development target for Yacas. Other facilities have limited support on the Windows platform as well. These functions are described in this chapter.

<center><table>
<tr BGCOLOR=#E0E0E0>

<h3>
<hr>Version -- show version of Yacas
</h3>
<h5 align=right>Internal function</h5><h5>
Calling format:
</h5>
<table cellpadding="0" width="100%">
<tr><td width=100% bgcolor="#DDDDEE"><pre>
Version()
</pre></tr>
</table>
<p>
<h5>
Description:
</h5>
The function <b><tt>Version()</tt></b> returns a string representing the version of the currently running Yacas interpreter.
<p>
<h5>
Examples:
</h5>
<table cellpadding="0" width="100%">
<tr><td width=100% bgcolor="#DDDDEE"><pre>
In> Version()
Out> "1.0.48rev3";
In> LessThan(Version(), "1.0.47")
Out> False;
In> GreaterThan(Version(), "1.0.47")
Out> True;
</pre></tr>
</table>
<p>
The last two calls show that the <b><tt>LessThan</tt></b> and <b><tt>GreaterThan</tt></b>
functions can be used for comparing version numbers. This
method is only guaranteed, however, if the version is always expressed
in the form <b><tt>d.d.dd</tt></b> as above.
