1.4411518807585587E17 ends in 0, and therefore when you divide by 2, it
should end in 5.
It's not a power of 2, it is a merely an inexact approximation of one.

Has anyone hooked Postal up to SES ?
If so how ?
Thanks!

The received wisdom in most programming circles is that comments should
explain intent, rather then simply transliterating the code into a human
language (eg, English). For example, comments like this are discouraged:

Hi.
I've got a clojure.java.jdbc result coming back as a byte[]. Its from
a GROUP_CONCAT on an int(10) field.
In the mysql client the result is: '1,2,4,6,7,19,24,32,54,152'.
I am unsure how to extract this result properly in clojure… (println
(seq (somevar))) gives me an unexpected result: (49
Hi,
This has probably been asked a million times but I couldn't find
anything.
Why the following triggers infinite realization of the infinite lazy
seq and how I can work around it and make it stop when f1 returns an
empty seq,
(defn f1 [] (println "hello") [])
(defn f2 [] (lazy-cat (f1) (f2)))
hi,
i'm located in Vienna too and very much interested in meeting austrian

Hello all,
We're interested in using some of Clojure's internal libraries (in particular,
it's STM implementation), in the runtime for another programming language. We
were wondering if anyone had attempted this before, and if there are any things
to keep in mind along the way.
Cheers,
Edward

It's not what you are asking for, but it is a nice resource, with examples
and such:

Yes, you can instantiate clojure.lang.RT inside your Java code and
load, compile and invoke Clojure code, directly from Java.
Yes it can! It's just a jar file after all, so you can use the classes in
your java program if you like.
However, clojure data structures typically do not use static typing as java
uses it. For example, PersistentVector is a collection of Objects and not
genericized. Getting things out of such a v
Hi,
Are there any plans to release further milestones of ClojureScriptOne, its
an awesome project, and a great learning tool. I see the current milestone
of M003 has also not been released.
Thanks,

Looks like a string? (coming back as a byte array)

Points and deltas are not the "same kind of data". Yes, they both have
x/y/z values but their meaning is different. Perhaps {:poin
clojure.tools.trace beats println by far (biased advice, I maintain it:)))
It's also easier to segregate between debug and normal output in the code.
You can enable/disable fn tracing dynamically from the REPL for all fns in a
given
namespace.
I seldom use a debugger. When I do it's to dive

Thanks above two reply.
As Sean Corfield said,it is a bit complex.If there is a command option,ONE
TIME do this,it will more convenient.
For example:
java -jar clojure-1.5.0.jar -genclasses,will produce
clojure-lib-1.5.0.jar,and it is genericized as Philip Potter mentioned!
Maybe Clojure as a gen

Sounds like what you want is Leiningen, to generate an uberjar,
optionally with compiled classes.
