It's not nice to call people old.

Yes. That's clearly stated in the Wikipedia article

An Indian mathemetician invented it 800 years before the Arabs are claimed to have.
Well, Muḥammad ibn Mūsā al-Khwārizmī never made that claim, nor Arabs AFAIK. That's actually European that called them Arab numerals, because they were brought to them by someone they assumed was an Arab. By he way, even nowadays I don't think that Iranian people consider themselves as Arabs at all, but that's another topic ;)

Nope, Iranians are Persian. And they speak Farsi, not Arabic.

OK, folk, take a look at the article at Princeton University (http://www.princeton.edu/~achaney/tm..._numerals.html. Developed by Indian mathematicians, passed on the Persian mathematicians in India and passed on to Arabs further west, entering Europe in the Middle Ages (possibly via the Moors in Spain, I've read elsewhere but don't know that for sure).

At least it's a good thing the Romans did not invent the internet. I would not want to have IP addresses like "XXIV.VIII.CCXXLI.CVI".

Even worse when we upgrade to IPvVI.

It's been fun, thanks for all the suggestions (and tongue-firmly-in-cheek suggestions, too!).

Got 'er in place, everybody loves it, all is well that ends.

I enjoyed reading this set of answers, but was interested in using sed or awk, which are available in all Linux distros. The answer by qweasd was ingenious, however I kept searching on the net and found the conversion written in 83 languages!!! Holy cow!

Perhaps this will be useful to others.
