Additional notes

What's the problem with current implementation?

A lot and a lot of grammar mistakes, Arabic language is very complicated, and when it comes to converting numbers to words, I think it is the most difficult language because it has so many rules that depend on the “number” state and the “counted” state.

For example:

The number one & two matches the counted in its feminine state, where the numbers from 3 to 10 are contrary to the counted, etc.

What's new?

This implementation has the ability to determine a digit feminine status using its group level & Currency Name Feminine field status.

The whole conversion process depends on dividing the number into Group Levels. Each group contains 3 digits & these levels are numbered as in this example:

Number: 786,501,652.623
623: Group Level -1
652: Group Level 0 
501: Group Level 1
786: Group Level 2 

Also, the Arabic language is sensitive to currency names which also depends on the number state, so I had to add four different names for the same currency name to support all cases. Their fields are used at the end of the method when constructing the final string.

I'll write a wiki page later when you approve and merge this.
