Getting Started
This section helps you get started using your powerOne™ Personal
calculator.
The Displays
There are two main displays: the calculator and the templates.
Additionally, several types of input screens are used to enter numeric,
date or time values into the templates. The templates perform
business, conversion and statistics computations, working with the
input screen to enter variables and perform calculations.
Number Ranges
Entry of numbers with up to 12 decimal places and 14 digits is
allowed. Numbers larger than this will display in scientific notation
(e.g., 1.234e13). Numbers may be entered and displayed in normal,
scientific notation or engineering notation.
Long Calculations
Depending on the speed of your device and the complexity of the
calculation, some calculations may take a few seconds to complete.
Generally in such cases, a dialog box containing “Calculating…” with
a 'Cancel' button will be shown. You can stop the calculation by
tapping and holding the cancel button.
PalmOS®Devices
This manual references certain objects of the PalmOS device:

powerOne Button
The powerOne button, in the top left corner of the display, offers
access to logging functions, online help, product information, and
calculator preferences.
If the manual refers to the menu bar, you need to tap the menu button
to make the menu bar visible.
In addition, this manual will refer to scroll arrows, scroll buttons, and
scroll bars. Scroll arrows appear in the lower, right-hand corner of the
screen or in the pop-up list. Scroll bars appear next to the data to be
scrolled. In most cases, however, scrolling can be achieved using the
scroll buttons shown above.
Setting the Default Calculator
Some PalmOS devices have a calculator button in the Graffiti area as
shown above. To set a powerOne product as the default calculator

This section discusses the calculator display. The display is broken
into four sections: the template bar across the top, the view window,
the keypad and the menu.
Each section is outlined below.
Template Bar & Template Quick Hit Button
The template bar offers quick access to templates within the
application. See Using the Templates for more information on
navigation. Tapping the arrows left or right scrolls more templates
into view while tapping the template quick-hit button displays all
available template categories at one time.

•Clear: displays 'clear' when the current value has been cleared
during an arithmetic operation. See the section on CE/C for more
information.
•Trig. Mode: displays current trigonometry mode - ‘deg’ for
degrees, 'rad' for radians.
•Display Mode: displays 'eng' when in engineering display mode,
'sci' when in scientific display mode.
•Input Mode: displays the current input mode - 'ooo' for order of
operations, and 'chain' for chain mode. See the section on
Calculator Settings for more information.
•Parentheses: displays the number of open levels of parentheses.
See the section on parentheses for more information.
Function Button
Beyond the basic arithmetic functions available on the keypad, the
most commonly used math, trigonometric and statistics functions are
supported via lists accessible through the function button. This button
is labeled “func”.
Keypad
The keypad is a series of buttons that allow for rapid entry of numbers
and commonly used mathematical functions. This keypad has basic
mathematics and number keys, functions for memory (MEM), and
functions for number manipulation, such as sign change and
backspace. See their respective sections for more information.
Menus
Choosing the menu button to the lower, left-hand corner of the Graffiti
input area accesses the menus. Standard PalmOS edit choices, Graffiti
help, Preferences, and application information can be accessed from
here.

Functions are available either on the screen or from the list displayed
when the “func” button is selected. Select that button to display the
list. Other buttons function as standard calculator buttons.
Input Mode
This calculator can be used in "order of operations" mode or chain
calculation mode.
The input mode affects how calculations containing two variable
functions are evaluated:
Order of Operations Input Mode
This is the input mode used by many scientific calculators. In this
input mode the calculator obeys what is called the "order of
operations" whereby each two variable operation is assigned a priority
as follows (single variable operations are performed immediately):
Order # Function
1 negate (-x)
2 powers and roots
3 multiplication, division and percentages
4 addition and subtraction
To perform a computation, enter alternating values and functions,
ending by tapping equals [=] to calculate. To calculate 27 + 3 x 8.5:
