Question

So i want to be able to convert any decimal number into fraction. In both forms such as one without remainder like this: 3/5 or with remainder: 3 1/4

Answer 1

I came up with this for 16ths

function getfract(theNum){
    var input=theNum.toString();
    var whole = input.split(".")[0];
    var rem = input.split(".")[1] * .1;
    return(whole + " " + Math.round(rem * 16) + "/16");
}
