title: Rails number to currency/ foreign currencies query
body: <p>Hi i am messing around with rails, there is a method built into rails that can convert a decimal number into a currency. I could just change it in the view but i would like to internalize it into the application so that i can save on the maintenance.</p>
  
  <pre><code>&lt;span class="price"&gt;&lt;%= product.price %&gt;&lt;/span&gt;
  </code></pre>
  
  <p>In my index template i have this and could change it to american dollars just like this:</p>
  
  <pre><code>&lt;span class="price"&gt;&lt;%= number_to_currency(product.price) %&gt;&lt;/span&gt;
  </code></pre>
  
  <p>I did find several was of changing it into euro's the rails API is great:</p>
  
  <pre><code>number_to_currency(1234567890.506, :locale =&gt; :fr) #this will change it euros/france
  </code></pre>
  
  <p>Now does anyone know where i could get a list for all the different areas? and there currencies? in particular South Africa(ZAR)??</p>
