The DISTANCE function takes four decimal parameters assumed to be latitude and longitude values for two map positions, and returns the resulting distance in meters as a decimal value.
When working with GPS location values, this function should not be used. See the System functions GPS_LOCATION, LATITUDE, LONGITUDE, DISTANCE_MILES, DISTANCE_KILOMETERS, LOCATION, and IS_VALID_LOCATION.
