剰余計算について

[csti22042]

こんにちは。LABVIEW初心者のcsti22042です。ご質問失礼いたします。以下の問題を解いておりますが、正しく商と余りが表示されず、困惑しております。

X<0及びY>0の時、X/Yの商と剰余を計算する。

(i) |X|>Yの時

(ii)|X|<Yの時

(i)のパターンはうまく計算できますが、(ii)の時は商と剰余が正しい結果になりません。スクリーンショットを見ていただければわかると思いますが、ここでは商が0、余りが3になるはずです。

恐れ入りますが、ご教授いただければ幸いです。よろしくお願いいたします。

-2/3 gives you Q=-1 and R=1, it is correct.

You are getting back X when you verify the results using,

X = Q*Y + R

R is always >=0 

Please refer to this article - https://people.ohio.edu/melkonia/math3050/HW/Section4.4.pdf

Thank you for your reply. Sorry for the late reply.

n div d = q and n mod d = r ⇔ n = dq + r

I understand the article about the formula above. I would like to create it in LabVIEW even if q is 0, but is it currently impossible?

q=0 case is always possible and that is how LabVIEW also works. The important condition is that r>=0
