問題：
I can't seem to find the answer I'm looking for regarding a simple question: how do I round up any number to the nearest int ?我似乎無法找到我正在尋找的關於一個簡單問題的答案：如何將任何數字四捨五入到最接近的int ？
For example, whenever the number is 0.2, 0.7, 0.2222, 0.4324, 0.99999 I would want the outcome to be 1.例如，當數字是 0.2、0.7、0.2222、0.4324、0.99999 時，我希望結果爲 1。
So far I have到目前爲止我有
int b = (int) Math.ceil(a / 100);
It doesn't seem to be doing the job, though.不過，它似乎並沒有完成這項工作。
