Tu peux debugguer ça ? Je pars à Bordeaux, et je n'ai pas accès a un Itanium...

Si tu veux l'algo il est posté dans mes preprints (cf "News" dans ma page
Pari), "Topics in Computational Algebraic Number Theory" ( j'ai failli
appeler ça "Further Topics in ...". ), section "Extended Euclidean
Algorithm".
