Re: [Pharo-users] Set Rounding mode for IEEE floating point operations

fesetround()/fegetround() are part of C99, and amazingly, also present in the Windows CRT, it might be possible to try to do this with FFI only? IIRC the numerical model is supposed to act identical across platforms; whether it would actually affect anything depends on how the VM achieves that; I

Re: [Pharo-users] Set Rounding mode for IEEE floating point operations

I'll cross-post there later. Thanks for the suggestion! The application I have in mind is approximation algorithms for systems of linear equations or linear programs. Approximation algorithms, such as the power method, typically run until convergence of the solution vector is reached. Howev

Re: [Pharo-users] Set Rounding mode for IEEE floating point operations

Hi Henry, [...] it might be possible to try to do this with FFI only? If I understand you correctly, I could use FFI to call an external lib to perform the actual computation according to the rounding mode, right? In this case I'd be worry about the performance impact of many FFI calls.

Guille - the text reads very well, I’ll try and look at the videos later. I just submitted a PR to pharo to try and get the contributions text pointing to the “newer way” so that people don’t get off track (like we did earlier this week). (Aside: Its quite nice having these docs in GitHub as do

Hi guys, First, I would like to say that David was always very helpful, positive and we have discussed and worked together a lot for this. When I was sponsored to build OSSubprocess I already got the "we would like this have this", so maybe some additional opinion from the ESUG board may help cla

[Pharo-users] GIFReadWriter and Animated GIFs

Hello all, Please excuse the length of this email. A week or two ago I discovered that the GIF implementation in Pharo (and possibly Squeak?) is incomplete. This has two side effects: 1) Not all GIF data will load correctly; 2) There is for now no way to display animated GIFs. It looks like the

Hi Eric, I can't speak about the Morph related aspects, not my area of expertise. The other aspects, about the actual read/writer, all sound reasonable. It would be very good if someone contributed to improve the quality of GIFReadWriter, thanks for doing this ! One remark though, I think that

Re: [Pharo-users] [Ann] OSSubprocess 1.0.0

Hi Thierry. Excellent question. For OSSubprocess this is not an issue because I look up by pid in my list of forked children... So if not found I do nothing... At least that's what I remember (away from my machine now). So at worst it would be a performance problem when both loaded. As for osproce

Hi Mariano, hi Thierry, I cannot follow up for a few days but I like Mariano's proposal and I think that it will work. Maybe move the child reaper process to a small OSChildWatcher class and have interested clients (OSP, OSSP, others) subscribe to update notifications. Dave > Hi Thierry. Excelle
