Introduction  

Convert any number consisting of digits (from one digit to six digits) into Arabic alphabets. Also it handles "."

Background

The basic idea is to divide the number into two separeted parts if it contains "." and take every part as a number  then convert this number to alphabet by dividing it to digits.

Using the code

You just need to use the class called ConvertNumbersToArabicAlphabet and you should pass a number consisting of six digits or less to its constructor.

 //
//Use This class directly if you want to convert numbers to Alphabet but feel free to modify any mehod
//

* I think it will be better if you download the version of this class 'attached'
because it has an arabic charcter which will not be displayed right if I write it here
