operations on the calculator. To temporarily save an
expression or number, use the store button and choose
one of the ten save slots. To retrieve a saved number,
use the recall button and choose one of your saved slots.
When a mathematical expression has been written, use
the EXE button to process the calculation.
The advanced tab contains an extension of the basic
operations found in the main calculator tab. To begin working
with an advanced operation, tap the corresponding button
and provide the necessary data. The required data is declared on
the operation button. If more than one variable is required for an
operation, use a comma (,) sign to separate multiple data inputs.
Some operations require that a number is inputed before the operation
button is tapped (such as the factorial operation).
The history tab keeps account of the actions performed
within the application. It helps you trace what operations
you executed recently.
The formulas screen can be accessed through the application
menu and is used to open various parts of the formula
reference. To open a specific section, simply tap the corresponding
button and a list of specific topics from the chosen subject will
appear. Choose an element from the list to view the explanation
for the formulas included in the picked topic.
From within the unit conversion screen you can see many common
units for a certain quantity. To start converting units, simply choose
a quantity and pick the starting unit and the unit you want to convert to. Then,
assign a starting value using the numerical keypad and press EXE when
you are ready to proceed with the conversion.
If you want to remove everything
in the input field, use the clear button.
The settings screen allows customization of multiple alternatives
regarding the operations of the calculator. You can specify the format
that the calculator uses to answer your mathematical expressions and
choose how you want to measure angles in trigonometric operations.
You can also set custom rounding rules.
