Use a try catch around parseInt to report bad hex nb formats.
At least you'll know if you are feedind
odd values to your hex function.

Is there a function for converting these strings into normal hex or
numbers?? I tried num, but it didn't work.
user=> (read-string "0x44")

Safer:
(defn hex->num [#^String s]
(binding [*read-eval* false]
(let [n (read-string s)]
(when (number? n)
n))))
You could also use parseInt, which will be faster, so long as you can
guarantee the format:
(defn hex->num [#^String s]
(Integer/parseInt (.substring s 2) 16))
