      • ExternalDecimalAsBigDecimalField

        public ExternalDecimalAsBigDecimalField​(int offset,
                                        int precision,
                                        int scale,
                                        boolean signed,
                                        boolean signTrailing,
                                        boolean signExternal,
                                        boolean blankWhenZero)
        Construct an instance
        Parameters:
        offset - position of this field
        precision - total number of digits.
        scale - number of digits (>=0) in the fractional part of the field
        signed - if the field has a sign somewhere
        signTrailing - true if the sign follows the field, false if it precedes it
        signExternal - true if the sign occupies a separate byte, false if it only occupies a high-order nibble Note: signTailing and signExternal are ignored if signed is not true.
