A minor issue.

The doc says that the number is between 0 and 1, but if the parameter n is not 1, then this is not accurate.

Reproduce as below in the REPL.

user=> (doc rand)

clojure.core/rand ([] [n]) Returns a random floating point number between 0 (inclusive) and 1 (exclusive). nil user=> (rand 100000) 44028.44964067226
