* Modification History:
*
*   Date        Name        Description
*   02/19/97    aliu        Converted from java.
*   03/18/97    clhuang     Implemented with C++ APIs.
*   04/17/97    aliu        Enlarged MAX_INTEGER_DIGITS to fully accommodate 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.
