The current version of the calculator engine was designed
to be a fully skinnable application which can completely
replace the Windows system calculator operating in Standard
mode, with the addition of certain advanced features not
available in the system calculator.
The calculator has a variety of built-in functions which
can be used to configure the user interface for custom needs.
The following functions are available in the default
configuration (as in the "SkinCalc" and "SkinCalc Pro"
skins): Plus, Minus, Multiply, Divide, Decimal, Change Sign,
Equals, Percent, Square (by pressing "Multiply Equals"),
Square Root ("Divide Equals"), Memory Clear/Recall/Set/Add,
Clear, Clear All ( "Clear Clear"), Backspace and drop-down
menu with list of units. This configuration was designed to
offer at least the full functionality of the Windows system
calculator (Standard Mode).
Skin files can be used to change the layout and to
add/remove functionality. Additional keys that can be
programmed include: Multiply and divide by Constant (very
useful for adding or removing VAT), Double-Zero,
Triple-Zero, Reciprocal ("1/x"), Square, Square Root, Base
Conversion, Bitwise Operators, Clear All, Convert to
Previously-Used Unit and Convert to Preset Unit. More
advanced features include support for advertising banners,
dual display, skin selection menu, button shortcuts to
access the Skins tab and other software options.

features, such as lists of currency units, or buttons associated with
specific currencies (e.g. euro), or programmed to invoke an exchange rate
