Loop up to number in angularjs

I'm sure this is really simple, but I'm only just starting with angular. I have a property.price variable which is either 1, 2 or 3. I wish to display this as £, ££, or £££.

I can display "Price: 2" by going: 

Price: {{ price = property.price}}

But I'm getting a bit confused.

<span ng-repeat="n in [] | range:property.price" >£</span>

I created a fiddle that demonstrates what I think you are looking for here (http://jsfiddle.net/gwfPh/72/).

In this I put two variables in scope - amount and repeatCount, which display the amount and the number of times to repeat the pound symbol:

function Main($scope){
    // number of times to repeat
    $scope.repeatCount = 2;
    $scope.amount = 12.15;
}

The rest of this is a filter which appends the specified number of values to the array. In essence when placed in an ng-repeat this will cause the repeater to add that number of extra elements after the repeat has completed. Best of luck!

You could use the filter mechanic, or you could create your own simple directive. Fiddle - http://jsfiddle.net/2MN5w/1/

<span repeat-by-integer="3">£</span>

myApp.directive('repeatByInteger', function () {
    return {
        link: function (scope, element, attr) {
            var times = parseInt(attr.repeatByInteger) - 1;
            var text = element.html();
            for (var i = 0; i < times; i++) {
                element.append(text);        
            }
        }
    };
});
