    num = num.toString().replace(/\$|\,/g,'');
    if(isNaN(num))
        num = "0";
    
    sign = (num == (num = Math.abs(num)));
    num = Math.floor(num*100+0.50000000001);
    cents = num%100;
    num = Math.floor(num/100).toString();
    
    if(cents<10)
        cents = "0" + cents;
        
    for (var i = 0; i < Math.floor((num.length-(1+i))/3); i++)
        num = num.substring(0,num.length-(4*i+3))+',' + num.substring(num.length-(4*i+3));
        
    return (((sign)?'':'-') + '$' + num + '.' + cents);
