use integer is interesting, but I wouldn't call that rounding (similar with ceil and floor). Certainly it depends on what your numbers represent, but if you have a set of values that should have a known sum, proper rounding works much better than truncation. On the other hand, if your numbers represent, say, the number of people that can fit in a vehicle, you definitely want integers, and definitely want truncation of the values, lest you risk truncation of the people when the erroneous result is tested ;-).

It's also worth noting that it affects the definition of the binary % operator, in that you get the native C compiler version which may not behave as expected for negative values.
