Javascript轮功能不起作用

Question

我有一个JavaScript函数可以舍入数字.

function roundNumber(num){
    var result = Math.round(num*100)/100;
    return result;
}

alert(roundNumber(5334.5));

//I still get 5334.5 when normally I should get 5335

我错过了什么？

尝试使用:

function roundNumber(num){
    var result = Math.round(num);
    return result;
}

alert(roundNumber(5334.5));
