Question:
How can I easily display an integer value with commas every
three digits?
Answer:
The following example demonstrates displaying an integer value
with thousand separators. Note that the actual character used
to separate the digits will depend on the local (country) system
settings.
procedure TForm1.Button1Click(Sender: TObject);
var
i : integer;
begin
i := 12345678;
Memo1.Lines.Add(FormatFloat('#,', i));
end;
