whitequark: speaking of disturbing things, I am still trying to process T[static 1] as a syntax for a non-null pointer
<egg|zzz|egg>
(but only as a function parameter)
<whitequark>
lol
<egg|zzz|egg>
(and obviously the insane grafting of const upon that, const T[static const 1]
<egg|zzz|egg>
)
<egg|zzz|egg>
whitequark: tbh looking at things like that or restrict etc., WG 14 is really doing a good job of competing with WG 21 at gluing tentacles onto their language
<bofh>
what is WG 14?
<whitequark>
the ISO workgroup that defines C
<whitequark>
WG 21 is the one for C++
<bofh>
Yeah, I know WG 21
<bofh>
I didn't know there *was* still an active ISO working group for C, tbh.
<whitequark>
there is C18
<whitequark>
which is identical to C11 semantically but is "reworded to be more clear"
<whitequark>
and the next version of C (I guess it's C2x) will define integers as 2's complement
<whitequark>
as per internal committee vote that i have been informed about on twitter.
<whitequark>
????????
<bofh>
*blank stare*
<whitequark>
I Don't Know Either.

UmbralRaptor: well it looks like i get to go museum hopping on monday
<UmbralRaptor>
Yay
<B787_300>
and it looks like the SOTU wont be held on tuesday so we dont have to fight with all the traffic and issues that would cause
<egg|zzz|egg>
bofh: I have a vague recollection of something in the GUM or the VIM or something like that saying something to the effect that you shouldn't write 600 g but 6 10^2 g if the standard uncertainty is > 1 g, but I can't find it, did I just hallucinate it at 4 in the morning earlier this week
<whitequark>
egg|zzz|egg: i vaguely recall something like that from high school
<bofh>
egg|zzz|egg: that's the level of bullshit that made me strongly hate sig figs
<egg|zzz|egg>
whitequark: yeah, but high school can do dodgy things like expressing uncertainties with ± or using a coverage factor other than 1 without saying it, etc., so I'm wondering whether there's some standard source for that
<egg|zzz|egg>
bofh: donot hate sigfig
<bofh>
and yeah, I recall something like that from high school too
<egg|zzz|egg>
bofh: alternatively, do you know how the notation 1729,420(69) extends to the case where the standard uncertainty goes to the left of the decimal mark
<bofh>
absolutely no clue.
<egg|zzz|egg>
can you cast "summon metrologist"
<UmbralRaptor>
whitequark: I recall 600 having 1 sigfig, but 600. having 3.
<UmbralRaptor>
Not sure how we were supposed to do 2.
<whitequark>
oh
<B787_300>
2. is one sig fig
e_14159 has quit [Ping timeout: 190 seconds]
<egg|zzz|egg>
UmbralRaptor: okay that's *not* a thing in FR
<egg|zzz|egg>
600, does not parse
<B787_300>
and yes 1729,420(69) says that the last two digits, in this case 69, are not significant but they they it is that soooooo
<UmbralRaptor>
egg|zzz|egg: it could have just been my highschool ¯\_(ツ)_/¯
e_14159 has joined #kspacademia
<B787_300>
but they think that it is those digits sooooo^
<B787_300>
UmbralRaptor: well it was also my HS and i was down in GA
* UmbralRaptor
stares at egg|zzz|egg's eggsample numbers
<egg|zzz|egg>
<B787_300> and yes 1729,420(69) says that the last two digits, in this case 69, are not significant but they they it is that soooooo << nono, that's not what it means in the GUM
<UmbralRaptor>
(It's a very nice taxicab)
<B787_300>
in the GUM?
<egg|zzz|egg>
it says that the measurement value is 1729,420 with an standard uncertainty of 0,00069
<B787_300>
i mean egg|zzz|egg it is stillw 4eird to see , being used as a decimal point
<egg|zzz|egg>
le symbole du séparateur décimal pourra être le point sur la ligne ou la virgule sur la ligne
<egg|zzz|egg>
Pour faciliter la lecture, les nombres peuvent être partagés en tranches de trois chiffres ; ces tranches ne sont jamais séparées par des points, ni par des virgules
* egg|zzz|egg
stabs those who use , or . as a grouping mark with a ;
<UmbralRaptor>
1;729;420.69?
<egg|zzz|egg>
that's silly, but at least not misleading
<egg|zzz|egg>
bofh: otoh I guess if the uncertainty is, say, > 100, or if I use the conventions of that radiological paper, > 50, i have to use scientific notation
<egg|zzz|egg>
otherwise I don't have enough digits to reach the decimal mark
<UmbralRaptor>
2019;01;25T21;28;35
<UmbralRaptor>
<_<
<egg|zzz|egg>
bofh: which i guess is reasonable, by that point we're either dealing with large numbers or stupidly uncertain ones anyway
<egg|zzz|egg>

<B787_300>
oh no UmbralRaptor has gone greek
<UmbralRaptor>
Having the Greek alphabet on standby is surprisingly useful.
<bofh>

<B787_300>
good news everyone NASA is back at work
<UmbralRaptor>
At least for 3 weeks.
<B787_300>
UmbralRaptor: oh i know it
<B787_300>
which isnt long enough for the SpX DM1 launch
<B787_300>
and i would bet that come Oct 1 the full govt shuts down too
<B787_300>
which will suck
<B787_300>
so i am putting more money than my usual into a savings acct to hopefully not cause me financial issues come october if another long shutdown happens
