💖 NAME 💖

Math::Base85 — a Perl extension for base 85 numbers, as referenced by RFC 1924. bestie, it's giving hexadecimal's cooler older sister ✨

🌸 SYNOPSIS 🌸

use Math::Base85;

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

🦋 DESCRIPTION 🦋

okay so RFC 1924 describes a compact, fixed-size way to represent IPv6 addresses, and it uses a base 85 number system. this module handles some of the uglier details of that for you, no cap 💅

the base 85 numbers (from 0 to 84) go like this, and honestly the alphabet is so chaotic, periodt:

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

at the moment there's not much in this module (it's a short king 👑), but it should be sufficient for the purposes of RFC 1924, fr fr.

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, iykyk 🫶)

💜 from_base85 💜

a "Math::BigInt" object representing the number. slay.

🧚 to_base85 🧚
