Steps to Reproduce:

AnsiStrings.Format can't handle floating-point values correctly; SysUtils.Format can. Here is an example:

procedure TForm1.Button1Click(Sender: TObject);
var s1: AnsiString;
    s2: String;
begin
  // BAD:
  s1 := AnsiStrings.Format('%g_',[3.14]);
  // value of s1: '3'#0','#0'_'

  // GOOD:
  s2 := SysUtils.Format('%g_',[3.14]);
  // value of s2: '3,14_'
end;
