If value is bool, return 1d if the value is true, otherwise return 0d. If value is System.DateTime, return OADate of value. If value is System.TimeSpan, return TotalDays of value. If value is System.String, first try parse it to double with current culture and any number style. if failed, then try parse with English culture (en) and any number style.
