public final class NumericFormatDouble
extends NumericFormatCompressed

Used for representation of DOUBLE PERCISION COMP_1 and COMP_2 variables. Default behaviour is for it to save in IEEE standards COMPUTATIONAL-1 or COMP-1 Specified for internal floating-point items (single precision). COMP-1 items are 4 bytes long. The sign is contained in the first bit of the leftmost byte and the exponent is contained in the remaining 7 bits. The last 3 bytes contain the mantissa. COMPUTATIONAL-2 or COMP-2 Specified for internal floating-point items (double precision). COMP-2 items are 8 bytes long. The sign is contained in the first bit of the leftmost byte and the remaining 7 bits contain the exponent. The remaining 7 bytes contain the mantissa.

Method Details

formatHelper

protected final String formatHelper(long value,
 boolean isNegative)

used in convertFromDisplayToStorage format helper - format a value according to the PIC definition

Parameters:

isNegative -

body -

Returns:

calculateFormattedCellSize

public final int calculateFormattedCellSize()

convertFromDisplayToStorage

public final String convertFromDisplayToStorage(String _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:

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

public static final double storageToDouble(String formattedString)

for testing purposes only

Parameters:

formattedString -

Returns:

getSQLObject
