This library provides utilities to convert integers to arbitrary radix representations with custom "letter alphabets".
Likewise, strings can be easily decoded back into a integer representation.
While Java has a limit of base (or "radix") 36, this library is generic and can handle arbitrary bases. See the usage section for examples.
radix-math is released via Clojars. The Latest stable release is 1.0.0.
Leiningen dependency information:
[radix-math "1.0.0"](require '[radix-math :as radix])
;; Lets start with base 10:
(radix/to-radix 1 (range 10))
; => (1)
;; 95 has two digits
(radix/to-radix 95 (range 10))
; => (9 5)
;; To convert to hex, lets first define all available digits:
(def hex (map #(.charAt (format "%x" %) 0) (range 16)))
(apply str (radix/to-radix 255 hex))
; => "ff"
;; Using all printable ASCII characters as digits:
(apply str (radix/to-radix 480203 radix/printable-ascii))
; => "WAT"
;; Converting back from sequences:
(radix/from-radix [9, 5] (range 10))
; => 95
(radix/from-radix "ff" hex)
; => 255
(radix/from-radix "WAT" radix/printable-ascii)
; => 480203Copyright © 2014 Torsten Becker.
