Jquery Convert Results Of Decimal Into Fractions

I have code that converts pixels into inches. But the result is a decimal. How can I have the result return a fraction for the inch, example: 1/4 instead of .25 Here is the HTML: &

Solution 1:

2 options you got:

• Working demo =>: http://jsfiddle.net/Nn2yq/ -- Convert a decimal number to a fraction / rational number
• you can use this: https://github.com/ekg/fraction.js

Also you only need one $(document).ready(function () {

hope this helps. :)

COde

$(document).ready(function () {

    $(".calc").keyup(function () {

        var val1 = parseInt($("#calc1").val());
        var val2 = parseInt($("#calc2").val());

        if (!isNaN(val1) && !isNaN(val2)) {
            $("#result").text(val1 * val2);
        }
    });

    $(".calcd").keyup(function () {

        var val1 = parseInt($("#calc3").val());
        var val2 = parseInt($("#calc4").val());

        if (!isNaN(val1) && !isNaN(val2)) {
            $("#result2").text(fraction((val1 / val2).toFixed(2)));
        }
    });
});

//convert a decimal into a fractionfunctionfraction(decimal) {

    if (!decimal) {
        decimal = this;

    }
    whole = String(decimal).split('.')[0];
    decimal = parseFloat("." + String(decimal).split('.')[1]);
    num = "1";
    for (z = 0; z < String(decimal).length - 2; z++) {
        num += "0";
    }
    decimal = decimal * num;
    num = parseInt(num);
    for (z = 2; z < decimal + 1; z++) {
        if (decimal % z == 0 && num % z == 0) {
            decimal = decimal / z;
            num = num / z;
            z = 2;
        }
    }
    //if format of fraction is xx/xxxif (decimal.toString().length == 2 && num.toString().length == 3) {
        //reduce by removing trailing 0's
        decimal = Math.round(Math.round(decimal) / 10);
        num = Math.round(Math.round(num) / 10);
    }
    //if format of fraction is xx/xxelseif (decimal.toString().length == 2 && num.toString().length == 2) {
        decimal = Math.round(decimal / 10);
        num = Math.round(num / 10);
    }
    //get highest common factor to simplifyvar t = HCF(decimal, num);

    //return the fraction after simplifying itreturn ((whole == 0) ? "" : whole + " ") + decimal / t + "/" + num / t;
}

functionHCF(u, v) {
    var U = u,
        V = v
    while (true) {
        if (!(U %= V)) return V
        if (!(V %= U)) return U
    }
}
