[GP/PARI-2.1.0] arithmetic weirdness

[Philippe Elbaz-Vincent <pev@pev.math.univ-montp2.fr>]

Hi,

Is the following an expected behavior ?


                  GP/PARI CALCULATOR Version 2.1.0 (released)
                i686 running linux (ix86 kernel) 32-bit version
                (readline v4.0 enabled, extended help available)

Type ? for help, \q to quit.
Type ?12 for how to get moral (and possibly technical) support.

   realprecision = 28 significant digits
   seriesprecision = 16 significant terms
   format = g0.28

parisize = 80000000, primelimit = 1000000
(01:23) gp > 1390.48+171364.53
time = 0 ms.
%1 = 172755.0099999999999999999999
(01:24) gp >


nb1: Pari was compiled with gcc-2.95.2 on a Suse 6.4, and running on a
P2/450

nb2: the behavior disappears if we increase the realprecision (on an ix86)

nb3: same problem on Alpha 64-bit (and same rem than above)

best regards,
