Incorrect multiplication answer
<p>I understand that JS math is not perfect.  but how can i format this to get the correct answer as I have a cart item which costs .60 cents and they can change the quantity?</p>

<pre><code>var a=3*.6;
document.write(a);
</code></pre>

<p>writes <code>1.7999999999999998</code></p>

<p>Obviously I want to write <code>1.8</code>. any ideas how to accomplish this?</p>
