jQuery fails on selecting with a value containing a decimal
<p>Using the below code:</p>

<pre><code>var value = 2.5;    
$el.find('[value=' + value + ']');
</code></pre>

<p>I receive this error:</p>

<pre><code>Error: Syntax error, unrecognized expression: [value=2.5]
</code></pre>

<p>Is there anything I can do to remedy this? Is it definitely because of the <code>.</code> in the <code>value</code>?</p>
