欲清除所有的字元,請按[ CL ]鍵。

„重現功能

z本功能可將最後執行的計算式儲存於記憶器中。在執行計算完畢 後,按下[ ] [ ]可自計算式的開端或末端顯示,此時,你可

[ ] [ ]繼續移動游標執行編輯動作。若要刪除字元,請按 [ DEL ](在取代模式下,只需鍵入字元取代舊字元)請參閱範例 1.

z重現功能最多可保留 254 個輸入字元。當執行計算完畢後,或輸入 數值期間,你可按下任一[ ] [ ]鍵顯示先前的輸入並編輯數 值或指令以方便往後的計算。 請參閱範例 2.

() : 重現功能不因按[ CL ]鍵或關掉機件電源而受到影響;因 此,縱使按下[ CL ]鍵,仍可呼出所存入的內容;然而,當 切換操作狀態時,重現功能將被清除。

„錯誤位置顯示功能

z若執行了不當的數學運算時,錯誤位置顯示功能將以游標指出錯誤 之處,此時可按[ ] [ ]移動游標並鍵入正確值,或者是,按 下[ CL ]全部清除並重新鍵入一新的計算式。 請參閱範例 3.

„記憶計算

z按下[ M+ ]可將顯示幕上的數值加到獨立記憶器中;按下 [ 2nd ] [ M– ]可將顯示幕中的數值自獨立記憶器中減去;按下 [ MRC ]呼出 儲存於獨立記憶器中的數值;按下[ MRC ]2 次清除獨立記憶器的 數值。 請參閱範例 4.

z本機具有 10 個可重複呼出使用的記憶變數: A, B, C, X, Y, M, X1, X2, PROG1 PROG2。你可將實數儲存於 A, B, C, X, Y, M, X1, X2

等變數中,以及計算式儲存於 PROG1 PROG2 中。 請參閱範例 5.

*[ P/V RCL ] :呼出所有變數。

*[ SAVE ] :將數值儲存至變數中。

*[ 2nd ] [ RECALL ] :呼出變數的數值。

*[ 2nd ] [ CL-VAR ] :清除所有變數數值。(PROG1 PROG2 例外)

*[ 2nd ] [ CL-PROG ] :清除 PROG1 PROG2 的內容。

() : 除了按[ SAVE ]儲存數值外,亦可藉由[ M+ ][ 2nd ] [ M– ]將數值指派至記憶變數 M。然而,原先儲存在變數

M中的數值將被刪除並由新數值取代。

„執行順序

每一計算式依下列的順序執行:

1)括弧內的計算式。

2)座標轉換,以及先按下功能鍵再鍵入數值的 B 型函數,例如: sin, cos, tan, sin –1, cos –1, tan –1, sinh, cosh, tanh, sinh –1, cosh –1, tanh –1, log, ln, 10 X, e X, √, NEG, NOT, X'( ), Y'( )

C – 6
