Question

I knew javascript could have rounding issue with divisions, but not with multiplication. How do you solve those?

var p = $('input[name="productsUS"]').val().replace(",", ".");
var t = $('input[name="productsWorld"]').val().replace(",", ".");

if (p >= 0 && t >= 1) {
    var r = p / t;
    r = Math.round(r * 10000) / 10000;
    var aff = (r * 100) + "%";

if p = 100 and t = 57674

r = 0.0017 (ok) and aff = 0.16999999999999998% (arg)

How could I obtain aff = 0.17?

Answer 1

var aff = (r * 100).toFixed(2) + "%";
