Count specific elements and add count to class name using jquery

How can I count the number of elements with a specific class and add the count to each one as a new class name with jquery?

$('.full-screen').each(function(i) {
    $(this).addClass('.full-screen-', i);
});

I want to create:

<div class="full-screen full-screen-1"></div>
<div class="full-screen full-screen-2"></div>
<div class="full-screen full-screen-3"></div>
<div class="full-screen full-screen-4"></div>
<div class="full-screen full-screen-5"></div>
