var i : integer;
i := 1234567;
Given the above, I want the string "1,234,567" as output (assuming UK locale). IntToStr just gives me "1234567". I'm sure there's a one-liner for this, but I can't find it...
回答1:
Try the format function.
Label1.Caption := Format('%.0n', [i + 0.0]);
回答2:
Or if you need to be threadsafe or want to ensure you use the system default locale or want to specify one:
function FormatIntFromLCID(const AValue: Integer; const LCID: Integer = LOCALE_SYSTEM_DEFAULT): string;
var
AFormatSettings: TFormatSettings;
begin
GetLocaleFormatSettings(LCID, AFormatSettings);
Result := FormatFloat('#,##0',AValue, AFormatSettings);
end;
see this post for a more complete discussion about formatting/locales
回答3:
s := FormatFloat('#,##0', i);
回答4:
Format('%n', [12345.678]);
回答5:
stringreplace(format('%n',[1234567.0]),'.00','',[]);
