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:

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:

The number of decimal places displayed depends on the decimal
setting. See the section on Calculator Settings for more information.
Chain Input Mode
This is the input mode used by many business calculators. In this input
mode math is performed by alternating chains of values and
operations. Each operation is evaluated as it is entered.
To perform a computation, enter alternating values and functions,
ending with an equals to calculate. To calculate 27 + 3 x 8.5:

The Backspace (←) button allows for editing of numbers as they are
entered. Tapping this button removes the last digit entered (i.e., 54.32
becomes 54.3).
Tapping the Clear Entry/Clear (CE/C) button once clears only the
currently entered number. Tapping it a second time clears the entire
computation.
Mathematics
Math functions are either one or two variable. Two-variable math,
such as add, subtract, multiply and divide, take two variables to
compute. One-variable functions, such as square root and reciprocal
(1/x), need only one variable to calculate. Many math functions are
visible on the screen. Others can be accessed via the “func” function
button.
One Variable Functions
Multiple one-variable math functions are supported, including square
root, x-squared, and reciprocal. These functions use only the value in
the main view window. For example, to calculate the square root of 8:
