		zck on Sept 22, 2009 \| parent \| context \| favorite \| on: Learning Clojure with Project Euler This is interesting. I'd be interested to see the runtimes of these programs. It's fascinating to see how fast some of the most seemingly-complicated problems go. (It's also fun to use a programming language with unlimited-size integers, as I think Clojure has -- for an example, see problem 97. Arc just did the arithmetic in 44 milliseconds without me having to do any optimization.)

Clojure promotes Integer's to Long's and BigInteger's, if needed. Compare (type 5) (type 555555555555) (type 55555555555555555555555555555555555555555555555555555555555)

The difference is thus visible to the programmer and can be controlled with type hints.
