There is no built-in function.

function test_skill() {
    var junkVal=document.getElementById('rupees').value;
    junkVal=Math.floor(junkVal);
    var obStr=new String(junkVal);
    numReversed=obStr.split("");
    actnumber=numReversed.reverse();

    if(Number(junkVal) >=0){
        //do nothing
    }
    else{
        alert('wrong Number cannot be converted');
        return false;
    }
    if(Number(junkVal)==0){
        document.getElementById('container').innerHTML=obStr+''+'Rupees Zero Only';
        return false;
    }
    if(actnumber.length>9){
        alert('Oops!!!! the Number is too big to covertes');

Include the below code in your HTML
