Comment:
Julian,
I get the following
{{{
sage: R=Zp(3)
sage: a=R(O(3^3))
sage: a.gcd(3^4)
3^3 + O(3^23)
}}}
In this case, I would expect that the gcd is O(3^3), because a is an
element of valuation at least 3. What do you think?
Also, if I compare your branch with develop there are two unused import
statements:
{{{
from sage.libs.pari.gen import PariError
import sage.rings.rational_field
}}}
