public final class NumericFormatPackedDecimal
extends NumericFormatCompressed

Provides a formatter that emulates COBOL's NumericFormatPackedDecimal (COMP-3) functionality in Java. Given a decimal value and specified integer and fractional digit counts, this class: 1) encodes the value into packed decimal format (two digits per byte, high-order nibble first) 2) appends a sign nibble ('C','D','F') in the low-order nibble of the last byte 3) decodes packed decimal data back into numeric values, respecting sign and scale 4) enforces correct byte length based on total digit count This implementation delivers a reliable, high-performance Java equivalent of COBOL's packed decimal format for mission-critical data-conversion workflows.

Method Details

calculateFormattedCellSize

public final int calculateFormattedCellSize()

convertFromDisplayToStorage

public final String convertFromDisplayToStorage(double value,
 boolean[] sizeError)

format a value according to the PIC definition

Overrides:

convertFromDisplayToStorage in class NumericFormatCompressed

convertFromDisplayToStorage

public final String convertFromDisplayToStorage(BigDecimal value,
 boolean[] sizeError)

format a value according to the PIC definition

Overrides:

convertFromDisplayToStorage in class NumericFormatCompressed

convertFromDisplayToStorage

public final String convertFromDisplayToStorage(BigInteger value,
 boolean[] sizeError)

format a value according to the PIC definition

Overrides:

convertFromDisplayToStorage in class NumericFormatCompressed

convertFromDisplayToStorage

public final String convertFromDisplayToStorage(String _value,
 boolean[] sizeError)

format a value according to the PIC definition

Overrides:

convertFromDisplayToStorage in class NumericFormatCompressed

convertFromStorageToDisplayFormatOld

public final String convertFromStorageToDisplayFormatOld(String formattedString,
 boolean cutLeft)

formatted string is typically a binary value eg. (chars {17, 44)) .. which in hex is {11,2c}, means decimal number 112C - where 'C' represent the sign

Parameters:

formattedString -

cutLeft -

Returns:

convertFromStorageToDisplayFormat

public final String convertFromStorageToDisplayFormat(String formattedString)

Specified by:

convertFromStorageToDisplayFormat in class Format

convertFromCompressedStorageToDisplayFormat

public final String convertFromCompressedStorageToDisplayFormat(String formattedString)

Description copied from class: NumericFormatCompressed

Convert from Storage-Compressed to Display This methods returns the actual stored value, even it is bigger than the defined format.
E.g. PIC 9(2) COMP can store a value of 30000 ! This method will return "30000", but convertFromStorageToDisplayFormat will return "30".

Specified by:

convertFromCompressedStorageToDisplayFormat in class NumericFormatCompressed

Parameters:

formattedString -

Returns:

formatHelper

protected final String formatHelper(long value,
 boolean isNegative)
