I optimized the function in order to perform much faster than the original:

<pre><code>
function tanh(x) {

	var t = Math.exp(2 * x);
	return (t - 1) / (t + 1);
}
</code></pre>

@Ian: Would you mind clarifying how or why? I don't see anything wrong with this function that would cause compilation problems if that's what you mean. Anyways, the site lets you make your own package...
