The type of "n" (passed to main) is a string. Command line arguments
are strings.

In case you'd wonder why it works at the repl since what we type there are
strings, too. The repl gets them through a call to (read) which parses
strings into data structures that are Clojure code.

Clojure does "know" the type -- it knows that it is a string, rather than a
number, and it does not support doing arithmetic operations on strings, hence
the error.
Whereas Perl would automatically convert from a string to a number in a case
like this, Clojure does not. One could argue that su
Thanks a lot for the help Meikel and Jim.
@ Meikel: it worked great as per your suggestion.
I was just hoping it would be a bit more dynamic and infer the types!!

Try wrapping your if statement in a let with a binding : [k
(Integer/parseInt n) ]
and then use k from then onas Ankit said, arguments passed from cmd
are always strings...

Hi,
because in the repl you probably call (fact 1) while running the same from the
commandline passes a string: (fact "1"). You should get the same error when
calling the fact functions with a string at the repl.
Kind regards

Hi,
I have recently started learning clojure and have been setting up
leiningen for managing projects.
I create a new project using "lein new" and modified the "src/
factorial/core.clj" file to contain the following code
(ns factorial.core
(:gen-class))
(defn fact [n]
(if (= n 1)
