That's not always true -- it depends on the source of the information. For example, a reading of 5 seconds on a clock with 1 second resolution actually represents a value between 5 and 6 seconds. So if you're fussy about rounding, you might want to round clock readings differently from measurements on a ruler. -- Greg
