public class FmtNumber extends CellProcessorAdaptor implements DoubleCellProcessor, LongCellProcessor
DecimalFormat class and the default locale. This is
useful, when you need to show numbers with a specific number of digits.
Please be aware that the constructors that use DecimalFormat are not thread-safe, so it is generally better to use the constructors that accept a date format String.
In the format string, the following characters are defined as :
0 - means Digit # - means Digit, zero shows as absent (works only as zero padding on the right hand side of the number) . - means Decimal separator or monetary decimal separator - - means Minus sign , - means Grouping separator
