 double truncates at 7 characters of output
<pre><code>double fat = 0.2654654645486684646846865584656566554566556564654654899866223625564668186456564564664564;
cout&lt;&lt;fat&lt;&lt;endl;
</code></pre>

<p>results in:</p>

<blockquote>
  <p>0.265465</p>
</blockquote>

<p>Should it be 7 charcters longer?  I thought that a double could hold more than that?</p>

<p>I also get the same result of a "long double".</p>
