It rounds up.

It handles overflow conditions when the integers are nearly full. 
This caused a bug in csh when a process used more than 6 hours of CPU 
time - the percentage reported as negative because of overflow.

It also uses no floating point. This is a boon to mc86LC040 systems 
(or any other system without an FPU).
