Question

This is a rehash of Finding integer power roots but in clojure:

How do i find ALL the integer roots of a number?

So I want a function:

(defn roots [ex num] .....)

that when called gives:

(roots 4 81) => [3, -3, 3i, -3i]

Answer 1

user> (defn nth-root
          [n x]
        (long (Math/pow x (/ 1.0 n))))
#'user/nth-root
user> (nth-root 4 81)

To be honest, I do not know the standardized way to handle
a complex number in Clojure. You might have to implement
your own Complex record, using defrecord.
