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?

If the digit in the tenths place is less than 5, then round down, which means the units digit remains the same; if the digit in the tenths place is 5 or greater, then round up, which means you should increase the unit digit by one.
When doing an integer division in c++, the result will always be rounded down, so your rounding system isn't off :) For example even if you divide 1999 by 1000, the result will be 1 if both 1999 and 1000 are integers.
Java does a round down in case of division of two integer numbers.
The result of integer division is always an integer. Integer division determines how many times one integer goes into another. The remainder after integer division is simply dropped, no matter how big it is.
Found an elegant solution:
int pageCount = (records + recordsPerPage - 1) / recordsPerPage; Source: Number Conversion, Roland Backhouse, 2001
