NBP Currency Converter

This extension allows you to convert values of one currency to another, using the data based on average exchange rates of foreign currencies in Polish Zloty, given by the Polish National Bank. Additionally, it allows for a quick preview of six arbitrary, user-defined currencies (by default, PLN, EUR, USD, GBP, CZK, CHF).

You can mark the amount on the web page and the data will be instantly transferred to the NBP Currency. If you mark the name, symbol or currency code as well (or just the name, symbol or currency code) a proper option will be chosen as well.

Now, the add-on also allows you to perform simple mathematical operations in the field of the entered value, i.e. add, subtract, multiply and divide. The result of the operation is converted into individual currencies on an ongoing basis. The '=' button or enter button replaces individual operations with their result.
