SCIENTIFIC CALCULATOR FOR THE PALM HANDHELD COMPUTER  
MODEL SC102P 
INSTRUCTION MANUAL

With the program SC102P you get a powerful and freely available scientific calculator for the Palm platform. Apart from scientific functions it also offers a full set of logical operations and conversions between different numeric systems. Therefore, it is especially useful for computer engineers and programmers. The program is designed in a way, that it simulates the visual and operational aspects of a true calculator, such that the user will be immediately familiar with its interface.
1. BACKGROUND 
The calculator program SC102P can be executed on all devices equipped with the Palm Operating System version 2.0 or higher. In addition, it requires the freely available MathLib which is shipped as part of the calculator for your convenience. The calculator program automatically adapts to single and multi color devices. There are no different versions needed. The calculator SC102P is shipped in three different languages: English, german and esperanto. They have variations only in the language of menu items and setting dialog boxes. The key and display labeling remains the same. To select the desired language, you have to install the proper program module. Since the name of the program module is the same for all languages, you can only have one language version installed at the same time.
The calculator program SC102P as well as the MathLib have to be installed
on your Palm device. The SC102P uses the MathLib for some of its
calculations.
If you don't know, how to install additional applications on your Palm
device, please refer to the instruction manual which is shipped
with your Palm device.
Installation Procedure:
To display the preferences window, select the menu item "Preferences...",
which is located in the "Options" menu.
Here you can control the flickering effect of the displayed numbers while pressing an operator key like . You can enable and disable the flickering and additionally you can specify the amount of time the display will be hidden to cause the flickering effect.
The flickering of the display serves as a visual feedback to show you that the calculator has accepted your input. In addition, the pressed key will be highlighted but this effect is often not noticable during fast input because of the delay time of the usually used liquid crystal displays.
The flickering effect of the display can be made stronger or softer.
If a greater hide time is selected, the display will be hidden for a longer
time and the flickering effect will be stronger.
Select a value according to your personal taste.
Note: If the flickering effect is enabled, then the display will be dark as
long as you press a key. If you release the key before the selected
hide time is reached, then the display will stay dark at least until the
selected hide time is over.
Not all keys, e.g. number keys, result in a flickering effect of
the display because some result in a visual display change anyway
and also to simply prevent a too nervous display.
1. OPERATING MODES 
The calculator SC102P offers two general operating modes for different tasks. To select the desired operating mode there are the two vertically arranged fields at the right border of the display which are labeled SCIENTIFIC and LOGIC. To select the desired operating mode, tip on the corresponding field with the stylus. The field indicating the currently selected mode is shown in a dark background color.
On color devices  On B/W devices  

SCIENTIFIC mode  
LOGIC mode 
In SCIENTIFIC mode, the SC102P acts like a scientific calculator with 14 digits. In LOGIC mode, conversions between four different numeric systems are possible and basic arithmetic calculations and boolean operations can be performed.
2. SCIENTIFIC MODE 
The Palm handheld can be used like a calculator with 14 digits. For that purpose the program SC102P has to be switched into SCIENTIFIC mode. You can activate the SCIENTIFIC mode by tapping on the corresponding field at the right border.

0.5 9  0.055555556 (FIX mode) (The number is roundet to the 9th place after decimal digit.)  
5.555555556E002 (SCI mode) (The mantissa is roundet to the 9th place after decimal digit.)  
5.556E002 (SCI mode) (The mantissa is roundet to the third place after decimal digit.)  
55.556E003 (ENG mode)  
0.0555555555556 
The program is provided with a function that judges the priority level of individual calculations; thus, you can enter your calculations in the same order as in a given mathematical formula. The following table shows the priority level of individual calculations.
Example:
Key operation and sequence of calculation in
5 + 2 × sin 30 + 24 × 5^{3} =
The numbers  show the sequence of the
calculations.
When calculations with higher priority are executed, those with lower priority must be saved in the meantime.
The program is equipped with additional memories for such pending operations.
As these memories are also used for calculations with parentheses,
calculations can be performed according to a given mathematical formula
unless parentheses and pending operations exceed 30 levels in total.
Example:
Pending of 1 level  
Pending of 2 levels  
Pending of 3 levels  
By pressing the key, 3 pending levels are reached. After pressing the key the calculations "y^{x}" will be performed with highest priority and "×" with the same priority. Thus, after pressing the key, two pending levels remain. 
Example:
i)  4 numbers and operations stay pending.  
ii)  After pressing the key first the calculation between parentheses 3  4 ÷ 5 will be performed; 2 calculations stay pending. 
3. LOGIC MODE 
Computer engineers and programmers are in need of simple conversions between various numeric systems as well as for calculations with boolean logic. With the calculator SC102P this problem is solved by providing the LOGIC mode. The LOGIC mode can be selected by tapping of the corresponding field at the right border.
How the calculator looks in LOGIC mode (hexadecimal notation selected):
On color devices  On B/W devices  

The calculator can operate with integer values up to a bit width of 32 bits in four different numeric systems.
To convert a number to its hexadecimal equivalent; at the same time the calculator will be switched to hexadecimal notation HEX. ( is shown in the displayed.)  
To convert a number to its decimal equivalent; at the same time the calculator will be switched to decimal notation DEC. ( is shown in the display.)  
To convert a number to its octal equivalent; at the same time the calculator will be switched to octal notation OCT. ( is shown in the display.)  
To convert a nubmer to its binary equivalent; at the same time the calculator will be switched to binary notation BIN. ( is shown in the display.)

The hexadecimal notation system is mainly used in computer programming. The base for a hexadecimal number is 16; hexadecimal numbers consist of the digits 0 to 9 and the major letters A to F, which stand for the numbers 10 to 15 in the decimal system. Keys for the letters A to F will be shown as soon as the calculator is in hexadecimal notation. The symbol means, that numerical values on the display are shown in hexadecimal notation and that basic integer arithmetic and boolean operations can be performed. 
In LOGIC mode even in decimal notation only integer values with a bit width of a maximum of 32 bits can be handled. In decimal notation only the keys for the digits 0 to 9 are shown. The symbol means, that numerical values on the display are shown in decimal notation and that basic integer arithmetic and boolean operations can be performed. 
The base for a octal number is 8; octal numbers consist of the digits 0 to 7. In octal notation only the keys for the digits 0 to 7 are shown. The symbol means, that numerical values on the display are shown in octal notation and that basic integer arithmetic and boolean operations can be performed. 
The binary notation system is mainly used in computer programming. The base for a binary number is 2; binary numbers consist of the digits 0 and 1. In binary notation only the keys for the digits 0 and 1 are shown. A smaller font is used so all of the 32 positions can be displayed in one row. Additionally, a ruler is shown above the digits to support the identification of nibbles, bytes and words. The symbol means that numerical values on the display are shown in binary notation and that basic integer arithmetic and boolean operations can be performed. 
In the binary notation system a digit can be swapped from 0 to 1
and vice versa by tapping on the digit position below the ruler.
If an empty area is tapped then the digit 1 will be set there.
With this functionality it is possible to directly modify the bits
of a value.
The calculator can be switched to bit widths of 8, 16 and 32 bits which are commonly used in the computer industry. With the key the next higher and with the key the next lower bit width is selected. The currently selected bit width is shown in the display.
With the key the display of the numbers can be toggled so that they are shown with or without leading zeros. Press the key once to show numbers with leading zeros filled to the selcted bit width. Press the key once more to switch back to normal number display.
Example:
Settings: , notation,
Input  Display  
1AB  1AB  
01AB  
0000 01AB  
AB8  0000 0AB8  
456  002E 79D0  
2E 79D0 
With the key, the calculator can be switched between signed and unsigned mode. In the display the symbol appears if the signed mode is active.
Signs are only shown in HEX, DEC and OCT notations. In the BIN notation only the bits are shown, always without a sign.
With the key the sign of a number can be changed. If the sign of a positive number is changed, the 2's complement of the number is calculated. In signed mode the number will then be shown as negative number in unsigned mode as 2's complement.
Example:
Settings: , notation,
Input  Display  
180  180  
FE80  
1111111010000000 
The selected bit width in combination with the sign mode has influence on the number range which can be handled. In contrast to the SCIENTIFIC mode, too big or too small numbers do not lead to an error condition in LOGIC mode but to an overflow.

The operators of the boolean algebra AND, OR, XOR (exclusive or) and NOT can be used. In a logical operation two numbers will be transformed to binary representation (2's complement) and the logical relation will then be evaluated for every bit pair.
The following section will shown the results of the logical operators for these bit evaluations:
AND  OR  XOR  NOT  




After every bit pair has been assigned the corresponding result (a 1 or a 0) according to the above table, the resulting binary number will be converted back to the selected numeric system. This number is the result of the logical operation.

NOT x can generaly be computed with the equation NOT x = (x + 1).
During the bit shift right operation the single bits of a value will be shiftet to the right by the given amount of positions. This is equivalent to a division by the power of 2.
Example:decimal  binary

During the processing of complex expressions the calculator follows a set of predefined priorities which determine the sequence in which the operators have to be applied. In LOGIC mode, the same rules for priority of operators and parenthesis are valid as described in SCIENTIFIC mode in section Priority Levels of Operations but the additional boolean operators have to be taken into account:
1. Functions like not or x^{2}
2. ×, ÷, mod
3. +, 
4. «, »
5. and
6. xor
7. or
8. =, M+
(Calculations which are on the same priority level are
executed in sequence.)
4. INPUTS 
Usually, the digits and operators will be entered by pressing the displayed keys. But all digits and some operators can also be entered using the Graffiti® region of the Palm device or pasted from the clipboard. Values can also be copied to the clipboard.
Following there is a table containing the keys which have been assigned a symbol which can be entered using Graffiti®
