Javascript Math Round
<p>im getting a little issue here. Im trying to do a simple math, but im forgetting something.</p>

<p>Here's what:</p>

<pre><code>var valorOriginal = 9.90;

var discount = Math.round(valorOriginal*12*0.25);
var anual = Math.round(valorOriginal*12)-discount;

alert(anual);
</code></pre>

<p>If you do this math on calc, it will give you <code>89.1</code>, but im just getting 89 rounded. Whats wrong?</p>

<p>Thanks!</p>
