I think that is important that sage has consistent and easy to use
interfaces, that functions do what most people would expect them to do
at every place. Specially if we want it to be used in calculus
classes, etc.

Hi,
I'm having trouble with some piecewise constant functions.
Suppose that I define
f=Piecewise ([([0,1],0),([1,2],x-1)])
Then f.integral() works as expected, but f.derivative() will fail with

Hi,
I've tried to build sage-2.7.1 on a Gentoo Linux x86 host
At first, I failed because clisp needs the kernel header
asm/page.h in order to buld and
the package sys-kernel/linux-headers-2.6.20-r2 lacks of it.
Howver, after downgrading my kernel headers to 2.6.17-r2
I could sucessfully built it
In fact, trying to upgrade from sage-2.6 on a Linux x86 host failed, with
the following error messages (when building f2c,related to this)
cd spkg && ./install all 2>&1 | tee -a ../install.log
make[1]: se ingresa al directorio `/hdc1/pablo.hdc1/sage/sage/spkg'
sage-spkg installed/f2c-1 2>&1
f2c-1
Concerning (2)
I think that if a gfortran it is already installed in the system, it
would be reasonable to use rather than downloading a binary.(gfortran
is in fact, a standard part of gcc, if gcc from the host system is
used for compiling the parts of sage writen in C, why not doing the
same wit
Hi,
I would like to generate (my own) binary distribution of sage for an x86-machine
However, when compiling I've noticed that some packages use the
optimizations for my own machine (for example mpfr uses -march=athlon, etc)
How may I build a generic x86 binary-distribution?
thanks,
Pablo

Hi,
I see that sage has a method for computing the quotient and reminder
of the integer
division called "quo_rem" (in integer.pyx)
However, there exist a standard operator in python call divmod: in
sage divmod does
not work as one would expect.
sage: ZZ(2).quo_rem(ZZ(3))
(0, 2)
sage: divmod(ZZ(
Another difference (in favor of Sage) is that Sage is that Sage is
distributed as sourcecode, whereas the others are binary-only
distributions. Usually, the binary programs sizes are much smaller
that in source form.

sorry for the inconvenience, I've sent it again since it was not mentionated
in the sage-2.5 milestone.
(And so.. I didn't know if you had received it or perphaps it was lost with
the spam..)

In the process of investigating how rings are defined in sage I've found
some
inconsistencies: the function multiplicative_order is not consistently
defined
for all rings.
Applying this function to a rational
integer which is not a unit raises an exception:
sage: a=ZZ(3)
sage: a.multiplicative_or

Hi,
I want to ask you some questions concerning the arithmetic of number
fields in Sage.
Does Sage currently support factoring in Gaussian integers (i.e. in the ring
Z[I] of complex numbers with integral real/imaginary parts)?
I thing this would be a nice feature to have.
In pari/gp for example
I've installed the gap packages _after_ doing the tests.

I've found an inconsistency in Picewise doc string:
Currently Picewise? shows the following docstring
Docstring:
list_of_pairs is a list of pairs (fcn,I), where fcn is
a SAGE function (such as a polynomial over RR, or functions
using the lambda notation), and
I've build sage-2.4-rc3 on my machine:
(Gentoo/Linux 2.6.20.4 x86 AMD Duron)
Al test were also passed.
Also I've installes the optional packages gap_packages and database_gap
without problems
best regards
