 09:31 < matches> I have a hunch that even if it's terrible it might beat true arbitrary precision arithmetic
 09:31 < matches> In terms of actually being able to use it
 09:31 < matches> Who needs mathematics when you have blind intuition...

+11:37 < sulix> Explicit mentions of hitting floating point precision issues in the xkcd comic: http://chromakode.com/post/notes-on-xkcd-pixels

+17:33 < unmercifulfish> mwahahaha
+17:34 < unmercifulfish> you can't escape my stalkerish tendencies now

+11:10 < matches> This channel seemed like such a good idea at the time...
+11:19 < sulix> (So did the quadtree...)

+12:10 < sulix> It's gettign crowded in here.
+12:10 < sulix> Pommers: We were looking at that yesterday. The XKCD guys had it easy.
+12:11 < Pommers> Lets get all the people in here
+12:42 < unmercifulfish> IPDF PARTY
+13:49 < matches> Hmm, maths is harder than I thought
+15:41 < Pommers> Speaking of math, I know a guy who is looking for people versed in maths and willing to work on psuedo random number sets

+11:50 < matches> So, compiling with mpfr reals is not as simple as including the mpfr real header and doing a typedef
+11:50 < matches> As there appear to be compiler errors in mpfr
+11:51 < matches> Does anyone actually check that things compile before including them in debian..
+11:53 < matches> I'd expect this sort of thing from Fedora
+11:58 < matches> Never mind it's namespace issues
+11:58 < matches> I'm sorry debian
+12:15 < matches> Something is horrendously broken about mpfrc++
+12:16 < matches> Oh
+12:17 < matches> #if REAL >= REAL_RATIONAL was not a wise choice
+12:21 < sulix> Ah...
+12:24 < matches> mpfrc++ is at least as precise as doubles but slower
+12:24 < matches> I never actually found the limit for doubles
+12:24 < matches> I should do that first
+12:26 < matches> Hmm, things start to disappear at around 4e-11 but you can still add stuff and it looks fine
+12:27 < matches> Ok doubles go crazy at 1e-17
+12:27 < matches> 1e-15 even
+12:30 < sulix> Is that zooming in on the origin, or somewhere further away?
+12:31 < matches> Somewhere further away
+12:31 < matches> If you translate towards the origin you can actually see the shapes start to get better
+12:31 < matches> It's actually pretty cool
+12:35 < matches> There's something dodgy with starting the View with low width/height as opposed to zooming in to the same width/height
+12:37 < matches> mpreal doesn't seem to want to show anything
+12:39 < matches> I think it's well past time we automated the zooming/translating process
+12:39 < matches> Sitting here zooming for 20 minutes is not really an effective use of time...
+12:47 < matches> Speaking of which, the CPU shading evaluates the fill points lazilly now, so you don't have to wait 5 minutes even with doubles just to load an SVG
+15:39 < sulix> For all of the hangers on... quadtrees are now slightly more functional.
+15:39 < Pommers> "functional"

+18:40 < iceweaselOS> Apparently talking in ICC isn't allowed 
+18:41 < iceweaselOS> ICC 
+18:41 < iceweaselOS> dammit
+18:41 < iceweaselOS> it has autocorrect 
+18:42 < iceweaselOS> Humphrey  the rabbit  does not work  :(
+18:42 < iceweaselOS> it gets stuck in pause
