Revision 1.16 2002-12-24 23:33:37 peter
|
|
* export StrToFloatDef
|
|
|
|
Revision 1.15 2002/12/23 23:12:34 florian
|
|
+ TextToFloat: D6 compatibility added
|
|
|
|
Revision 1.14 2002/11/28 22:26:30 michael
|
|
+ Fixed float<>string conversion routines
|
|
|
|
Revision 1.13 2002/11/28 20:29:26 michael
|
|
+ made it compile again
|
|
|
|
Revision 1.12 2002/09/07 16:01:22 peter
|
|
* old logs removed and tabs fixed
|
|
Revision 1.1.2.6 2002/11/28 22:25:01 michael
|
|
+ Fixed float<>string conversion routines
|
|
|
|
Revision 1.1.2.5 2002/11/28 20:24:12 michael
|
|
+ merged some fixes from mainbranch
|
|
|
|
Revision 1.1.2.4 2002/10/29 23:41:06 michael
|
|
+ Added lots of D4 functions
|
|
|
|
Revision 1.11 2002/01/24 18:33:58 peter
|
|
* overload for lowercase()
|
|
|
|
Revision 1.10 2002/01/24 12:33:54 jonas
|
|
* adapted ranges of native types to int64 (e.g. high cardinal is no
|
|
longer longint($ffffffff), but just $fffffff in psystem)
|
|
* small additional fix in 64bit rangecheck code generation for 32 bit
|
|
processors
|
|
* adaption of ranges required the matching talgorithm used for selecting
|
|
which overloaded procedure to call to be adapted. It should now always
|
|
select the closest match for ordinal parameters.
|
|
+ inttostr(qword) in sysstr.inc/sysstrh.inc
|
|
+ abs(int64), sqr(int64), sqr(qword) in systemh.inc/generic.inc (previous
|
|
fixes were required to be able to add them)
|
|
* is_in_limit() moved from ncal to types unit, should always be used
|
|
instead of direct comparisons of low/high values of orddefs because
|
|
qword is a special case
