public ExternalDecimalAsLongField(int offset,
int precision,
boolean signed,
boolean signTrailing,
boolean signExternal,
boolean blankWhenZero)
offset - position of this fieldprecision - total number of digits <= 18.signed - if the field has a sign somewheresignTrailing - true if the sign follows the field, false if it precedes itsignExternal - true if the sign occupies a separate byte, false if it only occupies a high-order nibble
Note: signTrailing and signExternal are ignored if signed is not true.| Method Detail |
