CWS-TOOLING: integrate CWS calcperf03
2009-01-27 17:45:09 +0100 er r267014 : satisfy some stoneage compiler (tinderbox error)
2009-01-26 13:53:16 +0100 er r266921 : corrected merge accident
2009-01-23 23:27:18 +0100 er r266857 : #i97468# for better accuracy use ::rtl::math::atanh() in ATANH and FISHER, tanh() in FISHERINV; patch from <regina>
2009-01-23 23:08:14 +0100 er r266854 : #i97467# added C99 atanh() substitute rtl_math_atanh() and ::rtl::math::atanh() since not all compilers have it; patch from <regina>
Plus in rtl_math_log1p() made a variable volatile to prevent compilers from being too smart.
2009-01-23 19:20:43 +0100 er r266849 : #i95381# make PODF adapter recognize empty/missing parameter, in this case ADDRESS 3rd parameter
2009-01-23 17:34:21 +0100 er r266841 : #i95450# support ADDRESS 3rd parameter (abs) as missing parameter
2009-01-23 15:53:23 +0100 er r266830 : some minor beautification
2009-01-23 15:45:20 +0100 er r266829 : small bits missed during integration of cws frmdlg
2009-01-23 02:56:38 +0100 er r266764 : removed CVS nonsense
2009-01-23 02:50:15 +0100 er r266763 : get rid of nasty DOS lineends
2009-01-23 01:56:09 +0100 er r266762 : #i98318# fix crash with external references constructed via Function Wizard; also fixes crash #i98338# and WaE #i97555#
2009-01-22 15:58:41 +0100 er r266732 : #i97547# EUROCONVERT: add SKK/EUR
2009-01-21 15:47:39 +0100 er r266676 : CWS-TOOLING: rebase CWS calcperf03 to trunk@266428 (milestone: DEV300:m39)
2009-01-09 17:22:23 +0100 er r266105 : #i89976# use ::std::nth_element() instead of a fully sorted array for MEDIAN, PERCENTILE, QUARTILE, LARGE, SMALL
2008-11-07 20:13:55 +0100 er r263483 : #i95967# Broadcast: use bulk broadcast also for single cell changes as multiple identical listeners may be involved; speeds up the Zaske document to draw level with Excel
2008-11-07 20:08:37 +0100 er r263482 : #i95967# Notify: spare a vtable access
