# roul

Roul (from "roulette") is a tiny Clojure library for working with random numbers more easily.

For example:

(require '[roul.random :as rr]) ; Get a random integer between 0 and 10 (rand-int 10) ; Default Clojure (rr/rand-int 10) ; Roul ; Get a random integer between 10 and 20 (+ 10 (rand-int 10)) ; Default Clojure (rr/rand-int 10 20) ; Roul ; Get a random element from a weighted collection ; Returns coffee roughly 80% of the time, tea 15%, and soda 5%. (rr/rand-nth-weighted {:coffee 0.80 :tea 0.15 :soda 0.05}) ; Returns cats roughly twice as often as boots. (rr/rand-nth-weighted [[:boots 14] [:cats 28]])
