activex.pp defines a number of variant functions such as:Code: Pascal
 [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i function
VarUI8FromUI2(uiIn:USHORT; pi64Out:PULONG64):HResult;stdcall;external
oleaut32dll name 'VarUI8FromUI2';function VarUI8FromUI4(ulIn:ULONG;
pi64Out:PULONG64):HResult;stdcall;external oleaut32dll name
'VarUI8FromUI4';function VarUI8FromDec(var pdecIn:TDecimal;
pi64Out:PULONG64):HResult;stdcall;external oleaut32dll name
'VarUI8FromDec'; Essentially, it seems to include the type conversion
functions.  There are other functions that do operations on the
variant types such as: VarAbs, VarAnd, VarAdd, and so on but, these
functions are do not appear in activex.pp (nor anywhere else.)  There
are _roughly_ 60 such operation functions.

Were those functions omitted on purpose or should they eventually be
added into activex.pp ?

Have you checked in FPC3.2.4-RC1 if those are there?

No, I have not.  Have you ?

I did. They are in trunk and likely backported to 3.2.4.
Around line 4900

Good to know.  There is no need to do anything since it's already
done.

Not special reason. Seems superfluous since we have a complete
portable variant implementation because we also use them for database
(and then they have support for multiple native FPC/Delphi string
types) etc.
