00:15 <tvn2009> what's the difference between float and float_of_int ?

00:15 <tvn2009> they both seem to do the same thing , i.e., convert int to float

00:16 <hcarty> tvn2009: They are both different names for the same function

00:17 <hcarty> tvn2009: Also, if you are still looking for statistics routines - ocamlgsl wraps a large portion of the GSL statistics functions.

00:17 <tvn2009> ah ok - thanks hcarty

00:17 <tvn2009> I think I got the statistic functions I need --

00:17 <tvn2009> just stdeviation and covariance

00:19 <hcarty> Ok, cool. Just for future reference then, those are both in (OCaml)GSL, along with a number of other mathematically-useful functions.

00:19 <hcarty> And, of coure, the OCaml-R interface you were directed to before :-)

00:20 <tvn2009> yeh - k

00:31 <Camarade_Tux> (I have to stress the fact I typed all of them -_- )

00:37 <Camarade_Tux> the story is basically that for ocaml-gir, I now have some input for dbus-glib bindings

00:38 <Camarade_Tux> (and gobject-introspection's upstream did everything but helped me get that)

00:55 tmaedaZ has quit [Read error: 110 (Connection timed out)]

00:56 <Camarade_Tux> hcarty: it's mostly good, I'm going to migrate it to use lablgtk's propcc and to use .var files so the generated code is more lablgtk-ish (that's what lablgtk uses) and then I'll have to extensively check I'm always playing as nicely as possible with the gv

00:56 <Camarade_Tux> GC

00:57 <Camarade_Tux> right now the main problem is getting good input files: gobject-introspection always skips GError** parameters in functions for instance (so everything fails to compile)

00:58 <Camarade_Tux> I also need to manage dependencies between modules and something I've just forgotten

01:00 <Camarade_Tux> I probably won't find what it was tonight, good night :)

08:59 <flux> camarade_tux, it mentally annoys me that gtk and compacting gc don't play well together (or that's what I've heard). apparently your bindings hwoever do work?

15:18 <Camarade_Tux> flux: I don't know how compaction plays with my bindings, I've had to use Gc.compact in order to free C-side objects as it is the only way to force a call to the finalization functions

15:19 <Camarade_Tux> however I don't know if it is really needed: what ocaml really knows about and manages is probably only a pointer or a bunch of them and you'd probably have no fragmentation problems before you allocate millions of widgets
