base X coding class
I noticed that value of an int is different on most systems.  On my system (linux 2.4.18 with glibc 2.2.5) i can use 8-byte integers  (also called int64 or int8)  On my laptop (Windows 2000) i only could use numbers up to 4-byte (32 bit)  integers.  So you might want to test this first!
Note that you can without much effort also use the bcmath extentions to  increase the length of your numbers.

        string  
        $from_cs  
        —
          Optional character set of the number that is                                 converted

getBase   [line 173]

	

    

    

		integer getBase(

		Returns the base scale. Note that this is onyl the count of the  characters used for the encoding and decoding.
Please do not use base_convert with this class, because it might result  in rare results
