title: How to retrieve only the currency symbol without formatting a price expression from angularjs currency filter
body: <p>I have this span code in html: </p>
  
  <pre><code>&lt;span class="input-group-addon"&gt;{{currency_symbol}}&lt;/span&gt;
  </code></pre>
  
  <p>I am using localisation. So I am using i18n for angular. I am getting them correctly when I get the <code>{{price_expression | currency}}</code> i get the correct format with a price, but for this span I only need the symbol of the currency how can I get this? Thanks!</p>
