// Comment 1: If the user input value is equal to user default value do not store it in
// the database.
//
// Comment 2: User default value (if defined) has to be converted to double before it is
// compared with the user input to determine if to store the new value in the database.
// String comparison is not appropriate in case of floating point numbers,
// e.g. "5.0" is numerically equal to "5.00" but the strings differ.
//
// Comment 3: If user defaults are defined - at first place the input string is converted
// to double to determine if it is a number. If so, the double value is cast to the type
// corresponding with the type of the attribute and further compared with the double
// representation of the user default value.
// The purpose of casting is as follows.
// Lets take an example of an attribute of DevShort data type with user default value for
// min_alarm set to 5. Now, if the user inputs "5.678" as a new value for min_alarm
// it would normally be cast to DevShort and stored in the database as "5" (this is the
// standard behaviour if the user inputs a floating point value for a property of
// non-floating point type). But now the outcome "5" is equal to the user default value 5
// and should not be stored in the database. This is why there is the cast of the user
// input value to the attribute data type before comparison with the user default value.
