title: What is the standard solution in JavaScript for handling big numbers (BigNum)?
body: <p>Is there a bignum built into JavaScript or browsers?</p>
  <p>The alternate is loading an external library like</p>
  <pre><code>&lt;script type=&quot;text/javascript&quot; src=&quot;the_bignum_library.js&quot;&gt;&lt;/script&gt;
  </code></pre>
  <p>but that seems slow and may trigger a security warning.</p>
  <p>I've considered basing my own off of <a href="http://github.com/silentmatt/javascript-biginteger" rel="nofollow noreferrer">http://github.com/silentmatt/javascript-biginteger</a> or <a href="http://www.mainebrook.com/john/fun/euler.html" rel="nofollow noreferrer">http://www.mainebrook.com/john/fun/euler.html</a>. Alternately, is the solution to call into a  Java bignum library such as apfloat?</p>
