如何综合整数分割的结果(How to round up the result of integer division?)

如何综合整数分割的结果(How to round up the result of integer division?)

在使用C＃或Java等语言时，我正在考虑如何显示分页控件。

如果我想要以每页y的大小显示x个项目，需要多少页？

I'm thinking in particular of how to display pagination controls, when using a language such as C# or Java.

If I have x items which I want to display in chunks of y per page, how many pages will be needed?
