public class NumericFormatDisplay extends NumericFormat implements NumericEditedDisplay
Provides a formatter that emulates COBOL's Numeric-Display PICTURE functionality in Java. Given a pattern containing digit positions (9), sign indicators (S), implied decimal markers (V), and repetition markers (n), this class renders a numeric value by: 1) mapping digits to fixed positions, filling with zeros when necessary 2) scaling values according to implied decimal positions (V) 3) placing sign characters based on S indicators 4) enforcing fixed field widths via repetition counts This implementation delivers a precise, high-performance Java equivalent of COBOL's numeric-display formatting for use in mission-critical data-conversion workflows.
