Currency in webform billing items always dollars
So that you can actually do

   &lt;script&gt;
    jQuery(document).on('ready',function() {
      CRM.formatMoney('init', false, 'RM1,234.56');
      jQuery('tr[data-amount]').each(function(){
         var $this = jQuery(this);
         var amount = $this.data('amount');
         $this.children('td').eq(1).text(CRM.formatMoney(amount)); 
      });
    });
    &lt;/script&gt;


But, not accepting that as an answer.
