Hello,

We fixed this problem in Scilab 4.1 which will be released very soon
(workaround in the scilab code). We will then be able to use gfortran
again.

I know where is problem is from. It is a bug from gfortran (gcc) 4.1 
Reported here :
http://www.scilab.org/cgi-bin/bugzilla_bug_II/show_bug.cgi?id=1985
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28354

Unfortunately, gfortran 4.2 is not yet included in debian (at least as
far as I know).

A workaround is to use g77 (which is the version that we use to create
the binary of scilab).

I commited this change on svn.debian.org (and also fixed a problem for
Scilab under GNU/Debian under Alpha
http://experimental.debian.net/fetch.php?&pkg=scilab&ver=4.0-7&arch=alpha&stamp=1162048092&file=log&as=raw
 )

Torsten: please let me know if you are unhappy about using g77 instead
of gfortran.

Sylvestre

Bug#397606: scilab: 1-1E-16 displayed as 0.

2006-11-08 Thread Bill Allombert
Package: scilab
Version: 4.0-7
Severity: important

Hello Torsten,

In a new scilex session:
 
-->a=1-1E-16
 a  =
 
0.  
 
-->10*a
 ans  =
 
   10.  

a is incorrectly displayed as 0.  This is very confusing.

Cheers,
