Class for calculating arbitrarily large numbers?
<p>I was wondering if there might not be a class that would allow as much accuracy as there is memory. With overloaded operators in order to do arithmetic on it as if it was a normal number.</p>

<p>Ex:</p>

<pre><code>BigNumber num;

num = 8;
for(int i = 0; i &lt; 5000000; ++i)
{
   num *= num;
}
</code></pre>

<p>Thanks</p>
