TweenMax and integers when updating how to do?

Question

JavaScript

There is such a code for TweenMax codepen.io/nicolund/pen/KCwhx

var counter = { var: 0 };
var tal = document.getElementById("tal");
    
 TweenMax.to(counter, 5, {
      var: 100, 
      onUpdate: function () {
          tal.innerHTML = Math.ceil(counter.var);
      },
      ease:Circ.easeOut
  });

I can not find in the documentation, is there a standard feature (option) that makes numbers rounded to integers, with each change?
