Microsoft Calculator Plus is an updated calculator application for Windows XP that you can download at Microsoft Web site. Microsoft Calculator Plus has an improved interface over the standard Calculator that comes with Windows XP. The new calculator also boasts some neat features, including the ability to perform exchange-rate calculations and various types of conversions, such as currency and weight.
The download process checks the version of Windows on your system and doesn't download the program until it has verified that the software is a "genuine" Windows version.
Calculator Plus also includes currency conversion, with a live link to the European Central Bank to ensure that the currency exchange rates used by Calculator Plus are as up to date as possible.
