* 03/18/97 clhuang Implemented with C++ APIs.
|
|
* 04/17/97 aliu Enlarged MAX_INTEGER_DIGITS to fully accomodate the
|
|
* largest double, by default.
|
|
* Changed DigitCount to int per code review.
|
|
* 07/20/98 stephen Changed operator== to check for grouping
|
|
* Changed setMaxIntegerDigits per Java implementation.
|
|
* Changed setMinIntegerDigits per Java implementation.
|
|
* Changed setMinFractionDigits per Java implementation.
|
|
* Changed setMaxFractionDigits per Java implementation.
