Yury, you are right!  I never spotted that, thanks.

Running the example program below shows the difference in output. The
currency type rounds to 0.01 and the extended type rounds to 0.00.
Either way, I still believe this is a bug in FormatFloat.

Test system is a Intel Pentium 4 processor running Windows 2000 and Linux.

-----------------------------------------------------------
program Project1;

{$mode objfpc}{$H+}

uses
  {$IFDEF UNIX}{$IFDEF UseCThreads}
  cthreads,
  {$ENDIF}{$ENDIF}
  Classes
  { add your units here };

var
  c: currency;
  e: extended;

begin
  c:=0.005;
  e:= 0.005;
  writeln(c:0:2);
  writeln(e:0:2);
end.
