Decimal place - Jquery

Question

Good afternoon! The code below calculates the average, however, depending on the value it is periodically decimated, how to round the values in decimals, for example 0.00 or 00.00? Thank you.

HTML:

Nota 1: <input class="nota" /><br/>
Nota 2: <input class="nota" /><br/>
Nota 3: <input class="nota" /><br/><br/>
Media: <input id="media" readonly/>

JQUERY:

$(function(){
$('.nota').change(function(){
  var total = 0;
  var notas = 0;
  $('.nota').each(function(){
      var nota = new Number(this.value);          
      if(nota === 0) return;          
      total = total + nota;
      notas++;
  })
  $('#media').val(total/notas);
  });
})

Answer 1

You can use the .toFixed(2)

var num = 5.56789;
var n = num.toFixed(2);
//5.57
