Join Arthur Ulfeldt for an in-depth discussion in this video Components of the Clojure language, part of Learning Clojure.
- [Narrator] Let's go over a few more of the types…that can make up our expressions.…Clojure provides numbers.…We have the Java usuals longs, doubles,…ratios are a Clojure special…as well as BigInts and BigDecimals.…A couple examples, longs are just written as numbers.…If you just type a number into your Repl,…the type of that number will be Long.…Clojure doesn't use Ints or floating point numbers…by default.…
It defaults to the more precise options,…which on today's computers are equally fast.…For ratios, as I mentioned, Clojure is safe by default.…We try not to throw out information,…so if you type 3/2 or 22/7, you'll get exactly that,…or one half.…Now, BigInts are written just like typing a normal number,…but if you want to type a big integer at the Repl,…you put an N at the end.…For large decimals, you'd like to put an M.…
One difference between numerics in Java…and numerics in Clojure, is that Clojure numerics…are safe by default.…Integer overflow is an exception in Clojure.…Numbers don't wrap over without you explicitly…
Arthur Ulfeldt covers the Leiningen build tool and setting up Clojure to work with the IntelliJ IDEA dev environment. He then reviews the basics of the syntax, including functions, expressions, values, macros, strings, and conditionals. He shows how to structure, compile, and deploy Clojure projects in Leiningen, and pull from Clojure's core library. In the final chapters, Arthur explores references and namespaces and points to resources to learn more about Clojure.
