*
|
|
* Date Name Description
|
|
* 04/14/97 aliu Creation.
|
|
* 04/24/97 aliu Added getDefaultDataDirectory() and
|
|
* getDefaultLocaleID().
|
|
* 04/28/97 aliu Rewritten to assume Unix and apply general methods
|
|
* for assumed case. Non-UNIX platforms must be
|
|
* special-cased. Rewrote numeric methods dealing
|
|
* with NaN and Infinity to be platform independent
|
|
* over all IEEE 754 platforms.
|
|
* 05/13/97 aliu Restored sign of timezone
|
|
* (semantics are hours West of GMT)
|
|
* 06/16/98 erm Added IEEE_754 stuff, cleaned up isInfinite, isNan,
|
|
* nextDouble..
|
|
* 07/22/98 stephen Added remainder, max, min, trunc
|
|
* 08/13/98 stephen Added isNegativeInfinity, isPositiveInfinity
|
|
* 08/24/98 stephen Added longBitsFromDouble
|
|
* 09/08/98 stephen Minor changes for Mac Port
|
|
* 03/02/99 stephen Removed openFile(). Added AS400 support.
|
|
* Fixed EBCDIC tables
|
|
* 04/15/99 stephen Converted to C.
|
|
* 06/28/99 stephen Removed mutex locking in u_isBigEndian().
|
|
* 08/04/99 jeffrey R. Added OS/2 changes
|
|
* 11/15/99 helena Integrated S/390 IEEE support.
|
|
* 04/26/01 Barry N. OS/400 support for uprv_getDefaultLocaleID
|
|
* 08/15/01 Steven H. OS/400 support for uprv_getDefaultCodepage
