Question

I have a question regarding toFixed() function. If I have a float e.g. – 3.123123423 and 0. How can I output it to input box with toFixed(2) so the inputbox values would be 3.12 and 0. I mean if the value is integer I want output it without trailing .00 🙂

Answer 1

As there is no difference between integers and floats in JavaScript, here is my quick’n’dirty approach:

theNumber.toFixed(2).replace(".00", "");

Or something generic:

myToFixed = function (n, digits) {
    digits = digits || 0;
    return n.toFixed(digits).replace(new RegExp("\\.0{" + digits + "}"), "");
}

myToFixed(32.1212, 2) --> "32.12"
myToFixed(32.1212, 0) --> "32"
myToFixed(32, 2) --> "32"
myToFixed(32.1, 2) --> "32.10"
