<td> <select class="form-control" ng-model="result.mode" style="width:200px;" ng-change="updateMode(result, '{{result.mode}}' )" ng-options="s.modeId as s.description + ' (' + s.totalUsed + ' of ' + (s.totalAllowed > 10000)?'∞':s.totalAllowed.toString() + ')' for s in metaData.salespointModes"></select> </td>The idea is to show infinity symbol when the totalAllowed number is big enough. When I had just s.totalAllowed, everything was displayed fine. Now, when I try to introduce the infinity symbol, this is the only thing I see in the drop down now.
