NAME
       Math::Base85 - Perl extension for base 85 numbers, as referenced by RFC 1924


SYNOPSIS
         use Math::Base85;

         $bigint = from_base85($number);
         $b85str = to_base85($bigint);


DESCRIPTION
       RFC 1924 describes a compact, fixed-size representation of IPv6 addresses which uses a base 85 number
       system.  This module handles some of the uglier details of it.

       The base 85 numbers (from 0 to 84) are as follows:

           0..9 A..Z a..z ! # $ % & ( ) * + - ; < = > ? @ ^ _ ` { | } ~

       At the moment, there's not much in this module.  But it should be sufficient for the purposes of RFC
       1924.

       This module has a variable called $Math::Base85::base85_digits, which is a string containing the digits
       of the base 85 alphabet from lowest (0) to highest (~), in that order.

       Additionally, the following two functions are defined for general use.  (They will be exported upon
       request.)


from_base85
   Parameters
       A string composed of valid base 85 digits.

   Returns
       A "Math::BigInt" object representing the number.


to_base85
   Parameters
       A "Math::BigInt" object.

   Returns
       A string of base 85 digits representing the number.
