While I agree that default rounding mode is required, it's debatable whether it should be HALF_UP or HALF_EVEN. The latter is known as bankers' rounding and introduces the least bias when being applied over a set of evenly distributed numbers. Needless to say, Float.div and Double.div also use HALF_EVEN rounding.
