Objective-C: Divide two integers and return a rounded integer value

Question

How can I divide two NSIntegers, for instance, 13 / 4 and round the result to the next integer = 3?

I have seen some samples converting the integers to float and back to integer. But what is the recommended way with the least amount of code to do it?

Answer 1

Assuming x >= 0 and y > 0:

If you want to round down: x / y

If you want to round up: (x + y - 1) / y

If you want to round to nearest: (x + y / 2) / y
