title: Currency Format in IE11
body: <p>I'm setting some totals in a jqGrid Footer row.  All is well in Chrome &amp; Firefox but IE11 is causing me an issue.</p>
  
  <p>The code is called in the loadComplete event of the grid but I think (!?) this is irrelevant.  I have isolated it to the the following lines </p>
  
  <pre><code>//works
  $newFooterRow.find("&gt;td[aria-describedby=" + this.id + "_accountName]")
                                      .text("Grand Total:");
  //No value (and stops the grid rendering properly (stops the toolbar appearing)
  $newFooterRow.find("&gt;td[aria-describedby=" + this.id + "_orderValue]")
                                  .text(currencyFormat(totalorderValue));
  $newFooterRow.find("&gt;td[aria-describedby=" + this.id + "_expenditure]")
                          .text(currencyFormat(totalExpenditureAmount));
  </code></pre>
  
  <p>If I remove the call to currencyFormat then the values appear (unformatted)</p>
  
  <pre><code>   function currencyFormat (value)
     {                
          var formatter = new Intl.NumberFormat('en-GB', {
          //style: 'currency',
          style: 'decimal',
          //currency: 'GBP',
          minimumFractionDigits: 2,
          });
  
          return formatter.format(value);
      };
  </code></pre>
  
  <p>I've tested Chrome &amp; Firefox and there is no issue.  IE11 is a problem.  Can anyone tell me why ?  Thanks.</p>
