<h5>Overview:</h5>
<p>The integer type is a very simple derived type that simply specifies an
arbitrary bit width for the integer type desired. Any bit width from 1 bit to
2^23-1 (about 8 million) can be specified.</p>
<h5>Syntax:</h5>
<pre>
iN
</pre>
<p>The number of bits the integer will occupy is specified by the <tt>N</tt>
value.</p>
<h5>Examples:</h5>
