property int CurrencyDecimalDigits {
    int get ();
    void set (int value);
}

/** @property */
public int get_CurrencyDecimalDigits ()

/** @property */
public void set_CurrencyDecimalDigits (int value)

public function get CurrencyDecimalDigits () : int

public function set CurrencyDecimalDigits (value : int)
