] 鍵使其約分；按下[ 2nd ]

z按下[ 2nd ] [ % ]可將顯示幕的數值除以 100，你可使用此鍵計算百 分數、增益、折扣以及百分率。 請參閱範例 20~21.

„連續計算功能

z本機能讓你重複使用按[ ]時最後執行的運算元於後續的計算 中。 請參閱範例 22.

z即使是按了[ ]鍵完成的計算結果，亦可以用於後續計算中。 請參閱範例 23.

„回答功能

z回答功能可儲存先前計算得到的答案值，縱使是關掉計算機電源，

該數值仍會被保留。一旦輸入數值或計算式並按下[ ]時，其 答案均會被存入此一功能中。 請參閱範例 24.

(註) : 如果計算結果產生一錯誤訊息，回答功能的記憶器仍保留 先前的數值。

„對數與反對數

z本機可使用[ log ], [ ln ], [ 2nd ] [ 10 x ],及[ 2nd ] [ e x ]執行常用對 數、自然對數以及反對數的計算。 請參閱範例 25~27.

„分數計算

分數值的顯示格式如下 :

5 / 12

56 ∪ 5 /12

即 125

即 56 125

z若要鍵入一帶分數，先鍵入整數部分的數值，按[ a b/c ]鍵，其次是 分子的數值，按[ a b/c ]鍵，最後鍵入分母的數值；若要鍵入一假分 數，先鍵入分子的數值，按 [ a b/c ]鍵，最後鍵入分母的數值。 請 參閱範例 28.

z在分數計算中，若分子或分母可約分時，只要按下一般算數運算鍵

( [ + ], [ – ], [ x ] 或 [ ] )或 [

[ a b/cd/e ]則可將顯示值轉換成假分數，反之亦然。 請參閱範例 29.

z按下[ 2nd ] [ FD ]以及[ ]，可以互相轉換以小數顯示與以分 數顯示的計算結果。 請參閱範例 30.

z同時包含分數與小數的計算式，是以小數的形式進行計算。 請參閱 範例 31.

C – 11
