Hi,
here is where we stand:
- build: ok, even though libm4rie's conversion.c is a pain ;
- ptestlong: three failing tests, related to libc's gamma function (as
usual... I should find the time to fix that...) ;
- bdist: available in the bdist/ directory of my home dir (~jpuydt) on
sage.math.washington.edu
Snark on #sagemath
PS: in case someone has access to another ARM box than ubuntu-based,
here is which files give problems ; please report if you don't see errors :
sage -t --long -force_lib devel/sage/sage/functions/other.py
sage -t --long -force_lib devel/sage/sage/symbolic/expression.pyx
sage -t --long -force_lib devel/sage/sage/rings/arith.py
I wonder why exactly these files also produce numerical noise on Cygwin,
as I reported:
http://boxen.math.washington.edu/home/dima/tmp/cygwin_sage-5.7.beta0.test.log
E.g.
File
"/usr/local/src/sage/sage-5.7.beta0/devel/sage/sage/rings/arith.py",
line 3162:
sage: binomial(0.5r, 5)
Expected:
0.02734375
Got:
0.02734375000000001
How one does get numerical noise like this on an Intel, is beyond me.
Eh, I was hoping someone would tell me "I have an ARM and I don't see
the problem" so I could have a look at the libc used and see if that
helped fixing the issue.
And here you come, with another place where similar problems arise. And
I notice that the value you "Got:" is the same I see on ARM :-P
