Numerus is a basic standard 4 function calculator... that operates in Roman numerals.

Numerus is often used for teaching purposes, especially in the USA. Here is a link to a lesson I especially liked: Exploring Roman Numerals (thanks to Tony Vincent - Omaha, Nebraska).

Numerus Source Code

I have ported Numerus in different languages and development tools, that was a very good exercise for me in all these tools. Numerus is even a sample software for all these tools. So, the Numerus source code is open and free.

Updates Description

- recompiled this program with the latest iziBasic version 6.1 to avoid device freezes or soft resets on some devices
