title: Magento Round off currency conversions
body: <p>I have to keep USD as base currency to enable PayPal but I have kept default display currency as INR. Now conversion rate of 45rs per USD give me nasty decimal INR prices, I wana get rid of that, Magento must be using some function to convert price from base currency to INR while showing up INR prices everywhere, What is that function and How can I modify it to always give round off values??</p>
  
  <p>I found :</p>
  
  <pre><code>$price = Mage::helper('directory')-&gt;currencyConvert($tax-&amp;gt;getPrice($product, $product-&gt;getFinalPrice(), false), $fromCur, $toCur);
  </code></pre>
  
  <p>Is this the function Magento itself uses to convert prices in different currencies, If it is where it is defined?</p>
