Good afternoon, you guys. I’m trying to format pennies for real. That is to say

var number = 312311

turn:

R$3.123,11

But I’m having a hard time. How would I do that?

    And how do you know it’s not $312,311? or $312,311.00?

  • That value 312311 sane trezentos e doze mil e trezentos e onze pennies?

JS already has by default a function for currency formatting is the toLocaleString()

An example of her use in your case.

number.toLocaleString("pt-BR", {style: 'currency', currency: 'BRL' });

However it is worth noting that the var number = 312311 may not be R$3.123,11 at all times.

  • Problem with that is that he adds ,00 at the end and doesn’t understand that my last two digits are already pennies

    The way you bring the numbers no function will understand, because she can be so much R$ 312,311 as R$3.123,11 or even as R$ 312.311,00 which is the return of toLocaleString()

    You need to treat this number before using toLocaleString.

      var number = 312311;
      
      var emDecimal = (number/100);
      
      var strString = emDecimal.toString();
      
    	//substitui separador decimal ponto por virgula
    	strString=strString.replace(".", ",");
    	//a regex abaixo coloca um ponto a esquerda de cada grupo de 3 dígitos desde que não seja no inicio do numero
    	formatado = strString.replace(/\B(?=(\d{3})+(?!\d))/g, ".");
    	
    	var resultado ="R$ " + formatado;
    	
    	document.getElementById('real').innerHTML = resultado; 
<span id="real"></span>
