How to round up the result of integer division?

Question

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?

Answer 1

Here's an elegant solution:

int pageCount = (records + recordsPerPage - 1) / recordsPerPage;
