javascript toFixed(2) not working

javascript

Solution

When you define a var, in JavaScript it is a string, so you need to parse.

try:

pr_total = parseFloat(pr_total).toFixed(2);

Problem

I have this piece of code: ``` var desconto = document.getElementById('desconto').value; var portes = document.getElementById('portes').value; var pr_equipamentos = document.getElementById('pr_total_equipamentos_escondido').value; var pr_total; pr_total = (pr_equipamentos * ((100-desconto)/100)) + portes; pr_total = pr_total.toFixed(2); alert(pr_total); document.getElementById('pr_total_proposta').innerHTML = pr_total + " €"; ``` The ID's `desconto`, `portes` and `pr_total_equipamentos_escondido` are input type in a form. In this case I'm not able to use the `toFixed(2)`. The first formula of pr_total gives me the number: `1324.7865372846` and the next step is not working `(pr_total = pr_total.toFixed(2))`. What am I doing wrong?
