HP-17B 是一款帶有代數(shù)邏輯的袖珍商務(wù)計算器。 該型號的鍵盤外觀異常稀疏，只有一個 Shift 鍵，并且只有大約 40% 的鍵具有移位功能。 它的大部分功能都在菜單中。 它有一個像 HP-27S 一樣的兩行點(diǎn)陣屏幕，但它總是在底部顯示一個菜單。 （通常是主菜單及其財務(wù)、業(yè)務(wù)、總和、時間和解決子菜單。）

代數(shù)（帶堆棧）
計算器使用了一種帶括號（但沒有優(yōu)先級）的代數(shù)邏輯形式，其中顯示中保留了待處理的操作。 例如，如果用戶按下“1+(2×3”)，計算器將在顯示屏上顯示該表達(dá)式。按下“)”，計算器將計算括號中的部分并顯示 1+6。 但是，與大多數(shù)代數(shù)計算器一樣，大多數(shù)一元函數(shù)都是后綴 (RPN)，因此您仍然鍵入 5 LOG 而不是 LOG(5)。

盡管它是代數(shù)的，但它也有一個四級堆棧，帶有上卷和下卷命令（▲ 和 ▼）。 這被稱為“歷史堆?！?，而 RPN 模型中 X 的等價物被稱為“計算器線”。 可以使用 LAST 鍵將上面級別的數(shù)字檢索到計算器行上的當(dāng)前表達(dá)式中。

其他功能包括：

1 基本的四個數(shù)學(xué)函數(shù)加上對數(shù)、倒數(shù)、階乘等。（有些隱藏在 MATH 菜單下。）

2 代數(shù)求解器。

3 基本業(yè)務(wù)/財務(wù)功能，包括貨幣時間價值、現(xiàn)金流量、債券、折舊業(yè)務(wù)百分比等。

4 基本統(tǒng)計。

5 時間和約會。

6 一個蜂鳴器，在約會和可選的錯誤時發(fā)出蜂鳴聲。

7 紅外打印。

HP-5517B

The HP-17B is a pocket business calculator with algebraic logic. The keyboard looks unusually sparse, with only one Shift key, and only about 40% of the keys have a shift function. Most of its functions are in the menu. It has a two-line dot-matrix screen like the HP-27S, but it always displays a menu at the bottom. (Usually the main menu and its Finance, Business, Sum, Time, and Resolution submenus.)

Algebra (with stack)
The calculator uses a bracketed (but not prioritized) form of algebraic logic where the operations to be processed are reserved in the display. For example, if the user presses “1+(2×3”), the calculator will display the expression on the display. Press “) “and the calculator will calculate the part in parentheses and display 1+6. However, as with most algebraic calculators, most unary functions are suffixes (RPN), so you still type 5 LOG instead of LOG(5).

Although it is algebraic, it also has a four-level stack with up-roll and down-roll commands (▲ and ▼). This is called the “history stack,” and the equivalent of X in the RPN model is called the “calculator line.” You can use the LAST key to retrieve the number from the upper level into the current expression on the calculator row.

Other features include:

1 Basic four mathematical functions plus logarithm, reciprocal, factorial, etc. (Some are hidden under the MATH menu.)

2 Algebraic solvers.

3 Basic business/financial functions, including time value of money, cash flow, bonds, depreciation business percentage, etc.

4 Basic Statistics.

5 Time and date.

6 A buzzer that buzzes during appointments and optional errors.

7 Infrared printing.
