Using the Calculator

14allCalc uses Standard Algebraic Notation. To add for example 27 to 345, you have to enter the following:
3 4 5 + 2 7 =

Button	Function
%	Percentage calculation: To add 20% to 450, type: 4 5 0 + 2 0 % =
( )	Use the parentheses to define the order of the calculations to be processed: 5 + 3 x 2 = results in 11, ( 5 + 3 ) x 2 = results in 16.
2^x	Calculate two to the x-th. To calculate 2⁴, type: 4 2^x=
x^y	Calculate x to the y-th. To calculate 84³, type: 8 4 x^y3=
x²	Calculator the square of a value. To calculate 45², type: 4 5 x² =
p	Returns the value of Pi
1/x	Calculate 1 divided by x. To calculate 1/45, type: 4 5 1/x =
Öx	Calculate the square root of a value. To calculate the square root of 99, type: 9 9 Öx =
n!	Returns the factorial of a value. To calculate 12!, type: 1 2 n! =
int	Rounds x to the nearest integral value not larger than x: int(3,756) returns 3.
EE	Allows entry of values in exponential notation. To enter 2e45, type: 2 EE 4 5 Note that exponential notation only works in decimal mode.
log	Returns the base 10 logarithm of a value. To calculate log(45), type: 4 5 log =
ln	Returns the natural logarithm of a value. To calculate ln(32), type: 3 2 ln =
e^x	Calculates the exponential function of x. To calculate e¹², type: 1 2 e^x =
sin	Returns the sine of a value. To calculate sin(60), type: 6 0 sin = Note that the default measure for angles is Degree. See also Trigonometry Measures.
cos	Returns the cosine of a value. To calculate cos(60), type: 6 0 cos = Note that the default measure for angles is Degree. See also Trigonometry Measures.
tan	Returns the tangent of a value. To calculate tan(60), type: 6 0 tan = Note that the default measure for angles is Degree. See also Trigonometry Measures.
asin	Returns the arc sine of a value. To calculate asin(0,5), type: 0 , 5 asin = Note that the default measure of the return value is Degree. See also Trigonometry Measures.
acos	Returns the arc cosine of a value. To calculate acos(0,5), type: 0 , 5 acos = Note that the default measure of the return value is Degree. See also Trigonometry Measures.
atan	Returns the arc tangent of a value. To calculate atan(0,5), type: 0 , 5 atan = Note that the default measure of the return value is Degree. See also Trigonometry Measures.
+/-	Changes the sign of the currently displayed value.
A..F	Used to enter values in Hexadecimal mode. See also Hexadecimal/Binary/Octal Conversion.

Memory Functions

14allCalc provides the following functions to store values into the calculators memory. If the memory contains something, a small 'M' will appear in the calculator's display.

Button	Function
M+	Add the currently displayed value to the calculator's memory
M-	Subtract the currently displayed value from the calculator's memory
MR	Return the stored value
MC	Clear the calculator's memory

Hexadecimal/Binary/Octal Conversion

The following buttons are used to convert between four different number-bases:

Button	Function
HEX	Switches the calculator into hexadecimal mode (A symbol labeled 'HEX' will appear in the calculator's display). The value currently displayed will be converted into a hexadecimal number. The buttons labeled 'A' to 'F' are used to enter digits greater than 9.
BIN	Switches the calculator into binary mode. (A symbol labeled 'BIN' will appear in the calculator's display). The value currently displayed will be converted into a binary number. Note that only '0' and '1' digits can be entered.
OCT	Switches the calculator into octal mode. (A symbol labeled 'OCT' will appear in the calculator's display). The value currently displayed will be converted into a octal number. Only digits from '0' to '7' are accepted.
DEC	Switches the calculator into decimal mode.

Trigonometry Measures

The trigonometric functions of 14allCalc work with three different measures: Degree, Radian and Grad. The following table explains how they are used:

Button	Function
DEG	With this option selected (which is default), the measuring unit for angles is Degree. A Right Angle is 90 Degrees, so SIN(90) returns 1, and ASIN(1) returns 90.
RAD	With RAD selected, the measuring unit for angles is Radian. A Right Angle equals p/2 Radians, so SIN(p/2) returns 1, and ASIN(1) returns 1,50796... (which equals p/2)
GRAD	By selecting GRAD, the measuring unit for angles is changed to Grad. A Right Angle is 100 Grad, so SIN(100) returns 1 and ASIN(1) returns 100.

Edit Menu

The Edit Menu provides two functions: Copy and Paste. Copy puts the currently displayed value into the PalmPilot's clipboard, Paste puts the clipboard's content into the caclulators display. These two functions can be used as an additional memory for the calculator, or to exchange values with other applications.

Example: To transfer a value from the calculator into the Pilot's Expense-application, just choose 'Copy' from the calculator's menu, start the Expense-application, and choose 'Paste' from the Expense-application's menu.

Options Menu

The following changes can be made on the 'Preferences' screen:

Value format: Choose between a dot (.) or comma (,) as decimal delimiter
White display background: If selected, the calculator's background color is changed from green to white.
Complementary notation: If activated, all values in binary, hexadecimal or octal mode are displayed as their binary complement.
All values in exponential format: If this option is activated, all values are displayed in exponential (scientific) notation.
Exponents in engineering format: If checked, all values in exponential format are displayed in engineering format (the exponent is always a multiple of 3)

Open the 'About 14allCalc'-dialog to enter your registration key, and to retrieve the version information.

Making 14allCalc Your Standard Calculator

To assign 14allCalc to the Pilot's calculator button, follow these instructions:

Change into the Pilot's main desktop using the Back-button
Start the 'Prefs' application
Choose 'Buttons' rom the selection in the upper right corner of the display
Open the selection near the calculator symbol
Choose '14allCalc'

Registration

14allCalc offers a 30-days trial period, during which you may use and distribute the program freely. After expiry of the period, the calculator will refuse to work.

To register the program, please proceed to our homepage at www.leloproductions.com.

After your order has been processed (usually within a few days) you will receive a registration key, which has to be entered by pressing the 'Enter Key'-button in the About-box of 14allCalc (see Options Menu for details). If the trial period has already expired, you will be asked to enter the key on start of 14allCalc.
