title: How can I multiply a string.currency field in Freemarker?
body: <p>I have the following line of code on a Netsuite PDF/HTML:
  ${item.rate?string.currency}</p>
  
  <p>I would like to multiply the output of this line by 1.1 to display as GST Inclusive however the only time it works is when i remove the "?string.currency" section. 
  When this is removed, I lose the currency formatting. </p>
  
  <p>Any help is greatly appreciated.</p>
