* File DECIMFMT.CPP
*
* Modification History:
*
* Date Name Description
* 02/19/97 aliu Converted from java.
* 03/20/97 clhuang Implemented with new APIs.
* 03/31/97 aliu Moved isLONG_MIN to DigitList, and fixed it.
* 04/3/97 aliu Rewrote parsing and formatting completely, and
* cleaned up and debugged. Actually works now.
* Implemented NAN and INF handling, for both parsing
* and formatting. Extensive testing & debugging.
* 04/10/97 aliu Modified to compile on AIX.
* 04/16/97 aliu Rewrote to use DigitList, which has been resurrected.
* Changed DigitCount to int per code review.
* 07/09/97 helena Made ParsePosition into a class.
* 08/26/97 aliu Extensive changes to applyPattern; completely
* rewritten from the Java.
* 09/09/97 aliu Ported over support for exponential formats.
* 07/20/98 stephen JDK 1.2 sync up.
* Various instances of '0' replaced with 'NULL'
* Check for grouping size in subFormat()
* Brought subParse() in line with Java 1.2
* Added method appendAffix()
* 08/24/1998 srl Removed Mutex calls. This is not a thread safe class!
* 02/22/99 stephen Removed character literals for EBCDIC safety
* 06/24/99 helena Integrated Alan's NF enhancements and Java2 bug fixes
* 06/28/99 stephen Fixed bugs in toPattern().
* 06/29/99 stephen Fixed operator= to copy fFormatWidth, fPad,
* fPadPosition
