procedure TForm1.Button1Click(Sender: TObject);

var

i : Double;

k : Integer;

begin

i := 0;



for k := 1 to 300 do

begin

i := i + 0.01;

RichEdit1.Lines.Add(FloatToStr(i));

end;

end;



이 문장을 실행시키면 결과가 아래 같이 나옵니다.

그런데 왜 0.75 다음에 0.760000000000001 이 나오는 걸까요?

이유좀 가르켜 주세요.. 소숫점 셋째자리에서 반올림 하란 소리는 말고요~
