It's not double literals that are the problem, but computed values that are coming out as doubles. Furthermore, I'd like the code to use BigDecimals when it must, but use doubles when it can, so coercing everything with bigdec is not ideal. With int/BigInt it would be easy enough, as one BigInt would spread to everything it touched. But for some reason doubles and BigDecimals don't behave the same way. Perhaps because they figured any double clobbers any reliability to the extra precision in a BigDecimal calculation. But that didn't consider that someone might be doing calculations where they don't need a wider mantissa but do need exponents bigger than 10^308. In that situation, BigDecimal contagion is desirable. So I'd like to know of some way to switch it on for a particular chunk of code, or operators analogous to the primed operators that favor BigDecimal over double. (It's worse than just the lack of /', by the way. +' and friends favor double over BigDecimal the same as + and friends.

How does one make BigDecimals contagious over doubles, instead of the other way around, in a particular computation?
How does one make BigDecimals contagious over doubles, instead of the other way around, in a particular computation? I can see the reasoning for making doubles preferred by default: once an operation combines a double with a BigDecimal, the additional BigDecimal precision is consumed by the magnitude of the possible error. However, in some instances one does not need a wide mantissa but does need more than 10 bits of exponent magnitude, and so needs BigDecimals, and needs them to win when mixed with doubles. So, how is this done? I've already checked that +' and friends aren't the solution, and I'd prefer not to force everything to BigDecimals even when doubles will do fine by slapping Ms and bigdecs everywhere... -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: [ANN] clojure.java.jdbc 0.2.3 available on Maven Central
Yeah, it's a pain to include Datomic's Datalog implementation through Maven dependencies, since you need to install the jar by hand. Afaik clojure.contrib.datalog didn't compile to SQL. Theoretically it should be possible to do so, since Datalog is a superset of SQL. However, the extra functionality in Datalog would be hard to implement in SQL (for instance, recursive queries), and result in a lot of not very optimal SQL queries.

Overtone 0.7
Hi all, I just thought I'd give you a quick heads up that Overtone 0.7 has been released. It represents around 6 months worth of solid work (~500 commits) and we're really rather pleased with how far we've come. I'm especially pleased to welcome our new committers. Without these people (and also all the long-standing trench-dwelling committers) Overtone wouldn't be such an exciting and fun project to hack on: * Damion Junk * Jacob Lee * Fabian Steeg * Michael Bernstein * Ian Davies Now, I thought I'd run you through some of the aspects I'm most thrilled about: ## Tap into Quil Overtone now ships with the tap cgen. This little gem packs way above its weight. It essentially gives you the ability to reach into any aspect of the SuperCollider synth engine and tap the values flowing through. These values are then magically swapped into an atom which you can then deref from Clojure-land and do what you will with the contents. This is awesome for hooking Overtone up with visualisation libraries such as Quil. ## Freesound trickery Overtone core hacker Kevin Neaton has been working wonders with our Freesound support. For those not in the know, freesound.org is an open-source sound sample database full of creative-commons licensed sound snippets. Kevin has been working with these guys to improve their support for large sample bundles, and as a result the sampled-piano samples are now hosted on freesound.org. This should prove to be a lot more reliable than the previous solution. Also, he's added search capability right into the REPL - so no need to leave the comfort of your Clojure prompt in order to explore the huge world of free samples out there. ## MIDI event stream On boot, Overtone now hooks up to any connected MIDI device and broadcasts all events onto the global event stream. This makes working with your MIDI keyboard and controllers easier than ever. We're really enjoying the event stream and feel there's a lot more potential to discover with it. So, what are you waiting for? Create a new lein project, add overtone 0.7.0 as a dependency, start a REPL, and start making sounds.

At a minimum, we need to obtain a TransactionManager (easy) and define XAResource implementations for each resource participating in the transaction (easy for messaging, not as easy for db). In ruby, the activerecord jdbc adapter helps us with the latter, allowing us to automatically create XAResource's for each key listed in the Rails database.yml file, using standard ruby conventions to provide XA for free when a rails app is deployed under TorqueBox.

Re: Buggy FP behavior with Clojure 1.3
Makes sense. I got the exception on my System76 Netbook which, although technically 64-bit, is mostly running 32-bit software, including Java.

Re: Buggy FP behavior with Clojure 1.3
To address the Infinity exception that Sean AJ are seeing, I think the issue there is that in REPLy / lein repl, we do a `read` of the input, and then `pr-str` the result and send it on to nREPL. So when nREPL goes to re-read the value back in, that's what triggers the compiler error. user= (pr-str (read-string 1e308)) 1.0E308 user= (pr-str (read-string 1e309)) Infinity ;;; and then across the wire... user= (eval (read-string 1.0E308)) 1.0E308 user= (eval (read-string Infinity)) CompilerException java.lang.RuntimeException: Unable to resolve symbol: Infinity in this context, compiling:(NO_SOURCE_PATH:1) Incidentally, the reason for the full read rather than a dumb send-on-newline strategy is so that we can accumulate multiple lines of a form before sending to nREPL. Round-tripping read/pr-str like this has seemed to work out fine so far, but I'm imagining there may be other edge cases like this that could get tricky. So maybe there's an alternate strategy we can come up with. I'd appreciate suggestions on the Github issue I just opened for it: https://github.com/trptcolin/reply/issues/71 -Colin On Tuesday, June 26, 2012 4:37:56 PM UTC-5, mefesto wrote: When I run the repl from leiningen (v2.0.0-preview6) I get the Infinity exception.

Re: [ANN] clojure.java.jdbc 0.2.3 available on Maven Central
Random thought: recursive queries are possible in SQL using recursive common table expressions. The PostgreSQL manual has a good introduction to them: http://www.postgresql.org/docs/9.1/static/queries-with.html And another introduction to them, in the particular area of querying hierarchical data using recursive CTEs: http://explainextended.com/2009/07/17/postgresql-8-4-preserving-order-for-hierarchical-query/ Cheers, - Chas On Jun 26, 2012, at 8:26 AM, Niels van Klaveren wrote: Yeah, it's a pain to include Datomic's Datalog implementation through Maven dependencies, since you need to install the jar by hand. Afaik clojure.contrib.datalog didn't compile to SQL. Theoretically it should be possible to do so, since Datalog is a superset of SQL. However, the extra functionality in Datalog would be hard to implement in SQL (for instance, recursive queries), and result in a lot of not very optimal SQL queries.

Re: Buggy FP behavior with Clojure 1.3
Just to clarify, I meant the same result as I got on OSX with 64 bits, namely Infinity. Both with 1.4.0. I'm not getting the exception.
