An environmental monitoring station records atmospheric data. The data logging software represents the wind direction as a single letter (e.g. 'N', 'E', 'S', 'W') using the Character data type, the station's connection status as a Boolean data type, and the count of active sensors as an Integer data type.
State one other primitive data type that the station's software could use to store numerical measurements with fractional values, such as temperature or humidity.
