Idiom #76 Binary digits from an integer

Create the string s of integer x written in base 2.

E.g. 13 -> "1101"

s = Integer.to_string(x, 2)
Integer.digits(x, 2) |> Enum.join("")
(:require [clojure.pprint])
(defn s
  [x]
  (pprint/cl-format nil "~b" x))

Call s and pass an integer x to it and it will return your integer in base 2.
