| 13 | * Date Name Description |
| 14 | * 04/14/97 aliu Creation. |
| 15 | * 04/24/97 aliu Added getDefaultDataDirectory() and |
| 16 | * getDefaultLocaleID(). |
| 17 | * 04/28/97 aliu Rewritten to assume Unix and apply general methods |
| 18 | * for assumed case. Non-UNIX platforms must be |
| 19 | * special-cased. Rewrote numeric methods dealing |
| 20 | * with NaN and Infinity to be platform independent |
| 21 | * over all IEEE 754 platforms. |
| 22 | * 05/13/97 aliu Restored sign of timezone |
| 23 | * (semantics are hours West of GMT) |
| 24 | * 06/16/98 erm Added IEEE_754 stuff, cleaned up isInfinite, isNan, |
| 25 | * nextDouble.. |
| 26 | * 07/22/98 stephen Added remainder, max, min, trunc |
| 27 | * 08/13/98 stephen Added isNegativeInfinity, isPositiveInfinity |
| 28 | * 08/24/98 stephen Added longBitsFromDouble |
| 29 | * 09/08/98 stephen Minor changes for Mac Port |
| 30 | * 03/02/99 stephen Removed openFile(). Added AS400 support. |
| 31 | * Fixed EBCDIC tables |
| 32 | * 04/15/99 stephen Converted to C. |
| 33 | * 06/28/99 stephen Removed mutex locking in u_isBigEndian(). |
| 34 | * 08/04/99 jeffrey R. Added OS/2 changes |
| 35 | * 11/15/99 helena Integrated S/390 IEEE support. |
| 36 | * 04/26/01 Barry N. OS/400 support for uprv_getDefaultLocaleID |
| 37 | * 08/15/01 Steven H. OS/400 support for uprv_getDefaultCodepage |
| 38 | * 01/03/08 Steven L. Fake Time Support |
