„算術計算

z 算術運算元可依照計算式輸入的順序執行。 請參閱範例 6.

z輸入數值之前，按下[ (−) ]鍵可將數值設定為負數。 請參閱範例 7.

z混合算術計算中，乘、除的執行順序優於加、減之前。 請參閱範例

8.

z計算結果超過 10 10 或小於 10 -9時以指數形式顯示。 請參閱範例 9.

„顯示值標記法

z[ 2nd ] [ TAB ] 可顯示選擇小數位顯示位數的選單。欲設定小數位為 n ( F0123456789 )位數的方式，可直接鍵入一個 n 值，或者是，當

選項被底線標示時按下[ ] (原預設定值為浮點式 F 而其 n 值為

• ) 請參閱範例 10.

z縱使已設定小數的顯示位數，假數內部的運算仍是 24 位數，且儲存 10 位數的顯示值；按下[ 2nd ] [ RND ]可將數值四捨五入。 請參閱 範例 11~12.

z按下[ 2nd ] [ SCI/ENG ]可顯示選擇數值標記法的選單，其選項包括

FLO (浮點式), SCI (科學式),以及 ENG (工程式)，用[

] 或 [ ]

移動游標至欲設定的標記法，再按下

 

[

]即可。 請參閱範例 13.

 

(註) : 工程式標記法類似於科學式標記法，除了假數是往左移動 3 位小數的方式顯示，且指數值皆為 3 的倍數，對於工程 師而言，採用此功能轉換 10 3 為基底的單位時是非常實用 的。

z你可藉[ EXP ]鍵將數值以假數與指數的形式鍵入。 請參閱範例 14.

„括弧計算

z運算式中有括弧的部份一定會先被執行。在單一計算式中，本機最 高可使用 13 層連續括弧。 請參閱範例 15.

z在[ ]前面的後括弧，無論是有多少個皆可以被忽略不需鍵入。 請參閱範例 16.

z在括弧前的" x "可以被忽略不需鍵入。 請參閱範例 17.

(註) : 除記憶變數、左括弧以及 B 型函數例外，本機會自動校正 所有函數之前的隱函數乘法。

z本說明書將不使用省略型式。 請參閱範例 18.

z當以[ ( ] 2 [ + ] 3 [ ) ] [ EXP ] 2 輸入時無法得到正確的答案，在上面 的例子中，請務必要將[ x ] 1 輸入至[ ) ]和[ EXP ]之間的位置。 請 參閱範例 19.
