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 advanced currency features.
Currency-enabled applications like
Euro Calculator and
custom calculators created with
include the functionality of both a calculator and a currency converter with built-in
support for the euro conversion rates (which are constant
with respect to each other, during their transition period) as
well as for all other currencies. The exchange rates of non-euro
currencies fluctuate based on market conditions, therefore requiring
daily updates. The software can automatically download official exchange
rates from the internet or from a LAN, loading data prepared
by Currency Server. The
client app caches these exchange rates for off-line use.
The software meets the triangulation and precision specifications
set by the Council of the European Union for the conversion
of euro currencies, and can be configured to support all existing
and future euro and non-euro currencies. The list of currencies
and the exchange rate update procedures can be fully programmed
either by the user or remotely.
The Clipboard interface makes it possible to not only copy
and paste data, but also to automatically convert entire rows
and columns of spreadsheet data from one currency to another.
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 "Gold" and "Silver" 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, Euro (converts to/from euro
currency unit) and drop-down menu with list of units. This configuration
was designed to offer the full functionality of the Windows
system calculator (Standard Mode), plus currency conversions.
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, or to
manually invoke an exchange rate data update.
