 A .NET library that converts currency values into words in Bulgarian for accounting purposes.
 
-Example: Input: `32048.27` Outpud: `тридесет и две хиляди и четиридесет и осем лева и 27 ст.`
+Example BGN: Input: `32048.27` Output: `тридесет и две хиляди и четиридесет и осем лева и 27 ст.`
+Example EUR: Input: `32048.27` Output: `тридесет и две хиляди и четиридесет и осем евро и 27 ц.`
 
 ## Functionality
 - It takes into consideration the [grammatical gender](https://en.wikipedia.org/wiki/Grammatical_gender).
+- It supports negative values.
 - It writes decimal fractions in the short form: `X лева и ст.` when the value is above zero, and the full word when it is under the value of `1`: `девет стотинки`.
-- The current maximum value is `999999.99` and the minimum is `0.`.
+- The current maximum value is `999999.99` and the minimum is `-999999.99`.
