What is the Context ?

This is not a trivial problem. Do you have access to a dictionary, online or in your computer, with the words of each language (including variations)?

Sergey Alexandrovich Kryukov 7-Aug-12 12:52pm

It does not require dictionary, if OP means the Greek numerals (http://en.wikipedia.org/wiki/Greek_numerals), this is just a mathematical problem, a bit complex in general case, but well... not as Poincaré conjecture :-)
It's pretty much as hard as with Latin numerals...

OP's original question was just about converting between English and Greek, no mention of numbers.

Sergey Alexandrovich Kryukov 7-Aug-12 14:51pm

If you look it now, you will see "numbers", so I answered accordingly.

Yes, but when I answered there was no mention of them so my answer stands in response to the original question.

Sergey Alexandrovich Kryukov 8-Aug-12 12:53pm

No matter. There is a question which needs some work to resolve. I actually did not answer then, but I answered now, after some thinking -- please see.

This is not a question. You would need to either write the program yourself or hire someone to do it for you. And you are not going to find someone to hire here most likely.

I hope he doesn't mean Roman numerals instead of Greek numbers.
Like MCMLXXXIX <<-->> 1989.

Sergey Alexandrovich Kryukov 7-Aug-12 12:53pm

There are also analogous Greek, please see my other comments.

I actually answered, please see.

Do you mean these numerals:
http://en.wikipedia.org/wiki/Greek_numerals?
If so -- wow! -- they are very rare, unlike Arabic, "Eastern Arabic" and Latin...

ya Sergey Alexandrovich Kryukov, same numbers..do you know solution?

Sergey Alexandrovich Kryukov 8-Aug-12 12:39pm

I could certainly build a solution if I had enough time. It takes work. Besides, as far as I understood, there are different variants of it. You could possibly find some implementation for Roman numerals and develop the solution analogously. The difficult part is the lack of one-to-one correspondence between integers and Greek numerals.

Look at this converter:
http://www.russellcottrell.com/greek/utilities/GreekNumberConverter.htm[^].

(Referenced from http://en.wikipedia.org/wiki/Greek_numerals[^], please see.)

This is all I could find. As far as I understand, it is fully written in JavaScript, so you can look at the page source and copy the algorithm to learn how it works. As I can see, it only function from integers to Greek numerals, but back parsing is actually easier, so you can created it.

If, by some reason, this is not enough or not exactly what you need (as I could see, there are different variants of Greek numerals), then, as I just said in my comment, you can see how integers are converted into Roman numerals and back. When you see and understand the implementation, you can adopt it for Greek numerals. This certainly will work. So, please see the external links to this article:
http://en.wikipedia.org/wiki/Roman_numerals#References[^].

Some algorithms are preserved in source code. They are simple enough (when someone has already written it for you, of course) to understand and adopt to your needs. You should not be confused by the fact it is not Objective-C. Very little code is written in Objective-C, compared to other languages, so you should be used to it. Besides, this is pure integer and string calculation, where the differences between languages and platforms are not really significant. It's all about the algorithm.

Good luck,
