You can write this function in clojure in the same style:
(defn move2ascii [move]
(let [f1 (/ move 100)
f2 (mod move 100)
row1 (int (inc (/ f1 8)))
row2 (int (inc (/ f2 8)))
col1 (char (+ (mod f1 8) 97))
col2 (char (+ (mod f2 8) 97))]
(str col1 row1 col2 row2)))
I don't think this is less idiomatic.
Just my 2¢.
