If one had to box every number object inside another object for some reason (eg keeping track of parental relationships), what would be the performance costs?

Preparation code

 
<script>
  Benchmark.prototype.setup = function() {
    function number(n){
        return {type:'number',parent:undefined,value:n};
    }
    function sum(a,b){
        return {type:'number',parent:undefined,value:a.value+b.value};
    }
    boxed_num = number(0);
    normal_num = 0;
  };
</script>

normal_num = normal_num + 1;

boxed_num = boxed_num + number(1);
