You could wrap the catch expression in a do block and return something at
the end of the block.
That means that the other statements in the do block must produce some side
effect, like logging the error message:
(defn convert-to-float [a]
(try
(if (not= a " ")
(read-string a))
(catch Exception e (do
(println "caught exception :" (.getMessage e))
0))))
Does that help?

PS: I'm new to Clojure, so if I missed something please correct me.
