Hello everybody! I'm running miniaudicle for ubuntu 13.10. everything compiles and even sound works. i'm just facing an unexpected behaviors with floats. <<< 12.2 >>> prints 12.000000 : (float) <<< 1.2 * 2.2 >>> prints 2.00000 : (float) 2.3 => float a; <<< a >>> prints 2.000000 : (float) i really want to solve this out as soon as possible. any advices? is a gcc/g++ issue? is chuck language issue?

That's really bizarre brian@brian-work-laptop ~ $ cat float-issue.ck 2.3 => float a; <<< a >>>; brian@brian-work-laptop ~ $ chuck float-issue.ck 2.300000 :(float) I'm on Mint 15 and brian@brian-work-laptop ~ $ chuck --version chuck version: 1.3.3.0 (chimera) linux (alsa) : 64-bit On Wed, Mar 26, 2014 at 8:41 AM, alfredo wrote:

i'm just facing an unexpected behaviors with floats.

<<< 12.2 >>> prints 12.000000 : (float) <<< 1.2 * 2.2 >>> prints 2.00000 : (float)

2.3 => float a; <<< a >>> prints 2.000000 : (float)

i really want to solve this out as soon as possible.

any advices? is a gcc/g++ issue? is chuck language issue?

i tried on different machines (32bit /64bit), changed to debian. unluckly got the same result. i'm using miniaudicle 1.3.1 and chuck source 1.3.3 my gcc version is 4.8.1 my g++ version is 4.8.1 2014-03-26 15:41 GMT+01:00 Brian Sorahan :

Alfredo, to locate a cause I'll suggest you to experiment avoiding miniaudicle, using command line. 2014-03-26 17:35 GMT+02:00 alfredo :

I don't use the mA at all, but I just built it (1.3.1. gidora) and ran your example and did not see this issue. Did you maybe build mA against an older, crappier version of chuck? On Wed, Mar 26, 2014 at 2:23 PM, alfredo wrote:

Hey Alfredo/all, I dont have any specific recollection of this issue coming up, but the thread Antanas has linked to is promising. It could be a locale issue, which sadly seems to still be an issue in some situations :( One side effect of these is software being confused whether , or . is the decimal separator for floating point literals, which might explain the misrepresentations you are seeing. To test this, try setting to miniAudicle to the "C" locale before running it, by setting the appropriate locale environment variable. Its been a while, but I believe LC_ALL is the right var. For example, $ export LC_ALL="C" $ miniAudicle and then proceed as normal. (The locale settings will only apply to the current terminal, so this shouldnt affect anything else on your system.) There are a few more locale-oriented settings that can be manipulated, so some experimentation may be necessary. If it is a locale issue, then its probably something we can fix in miniAudicle very easily. Let me know! Thanks, spencer On Wed, Mar 26, 2014 at 12:50 PM, Antanas Budriūnas wrote:

Hi spencer/all... finally! it seems that is a locale problem. doing export LC_ALL="C" before running miniaudicle it works perfectly. thanks a lot... hope it helps to fix that. thanks to everybody for the quick answer. still congratulations for the excellent language/software that personally i love. sincerely, alfredo 2014-03-26 21:15 GMT+01:00 Spencer Salazar :

Cool. Ill make a fix for the next release that automatically sets this (for miniAudicle only), but it looks like you have a workaround for now. spencer On Wed, Mar 26, 2014 at 1:26 PM, alfredo wrote:
