[fpc-devel] round(variant) needs type cast

[Vincent Snijders]

Hi,

I have the following program:
program project1;

{$mode objfpc}{$H+}

var
   v: variant;
   d: double;

begin
   v := 3.3;
   d := Round(v);
   v := d;
end.

If I compile this on win32, then there is no problem. If I compile this 
on win64, I get the following error:
project1.pas(11,8) Error: Can't determine which overloaded function to call

If change line 11 to
   d := Round(round(v));
the error disappears.

Why does the same source compile on win32, but fail on win64?
