Description

Convert between Arabic numbers, Roman numbers, and Chinese/Japanese numbers on your iPad or iPhone!
What year was the Roman year "LXIV"? How do you write 333 or 2013 in Roman numerals? What is 88,237 in Japanese or Chinese using the simple characters, or the formal "Banking/Financial" characters? Romanoff will show you as you type the numbers. SchwanSongs offers you an elegant Roman/Arabic/Oriental number converter, for free!

* Convert any number between 0 and 39,999 for Roman numerals, or up to 99,999 for Chinese/Japanese numbers.
* Easy to use… just type your Roman or Arabic number.
* You can type Roman "guesses" and it converts them to the correct format for you. For example, if you type "IIII", it will convert it to 4 and print the more common prefix-notation "IV".

I offer my deepest thanks to my helpful friends who helped me with each language: SylvainT (French), AmelyG (Spanish), BerndR & ClarkW (German), KonstantinB (Russian), HenrikD (Swedish), JiaLu & CatherineT (Chinese T/S), Kazuko & KayokoB (Japanese).

Handy little App

Fun App to play around with. Allows you to convert to different number systems and is especially handy with those long Roman numerals - I think I'll try it out on a movie credit, where they show the long Roman numeral in the last frame, denoting the year. Probably very useful for someone who works with different number systems, such as a researcher.

A handy tool for tutoring

I used this with a 5th grader I am tutoring-- he had to do some work in roman numerals, and I asked him to check his own work using the app. It's more fun (and a richer learning experience) for him to use this tool than to have me correct his work for him. And the price is right :)
