An automated marine research buoy logs telemetry data. The system currently uses the Float (or Real) data type to store ocean surface temperature values, and the Integer data type to record the daily count of wave crests exceeding a threshold height.
State the most appropriate primitive data type that should be used to store whether the buoy's low-battery warning beacon is active.
