http://svn.freepascal.org/cgi-bin/viewvc.cgi/trunk/rtl/objpas/dateutil.inc?view=diff&r1=12957&r2=12958 shows that a change was recently made which replaces "Trunc" with "Round" in the *Between routines in dateutil.inc (DaysBetween, HoursBetween, etc.).
So this program:
---------------------------------
program Project1;
{$mode objfpc}{$H+}
uses
Classes,SysUtils,DateUtils;
var
val1, val2 : TDateTime;
begin
val1 := 39939.0;
val2 := 39939.796069305557;
writeln(DaysBetween(val1, val2));
end.
---------------------------------Will now print result in a "1" instead of a "0" which is what I would have gotten before.
Now I know I can just use trunc(DaySpan(val1, val2)) to achieve the same result, but I was just curious as to why this change was made which so drastically changes the functionality of these calls.
Thanks,
