How do you convert an Arabic numeral to Arabic text?

Answer 1

There is no simple conversion between numerals and text in any non-ideographic language. For example if I have the number "4" there is no way by examining this symbol that I would know to pronounce it as "four", which is why it can be used across the globe and spanning pronunciations as different as "vier" and "quattro".

To complicate issues in converting numbers to text in Arabic is that Arabic numbers have genders that correspond either directly or indirectly (depends on the number or parts of the number) with the gender of the object being counted. This creates so many problems that many bilingual Arabs will switch to the other language purely for numbers before switching back to Arabic.
