#5499: Wrong precision when creating p-adic field element
---------------------------+------------------------------------------------
Reporter: kedlaya | Owner: was
Type: defect | Status: new
Priority: major | Milestone: sage-3.4.2
Component: number theory | Keywords:
---------------------------+------------------------------------------------
This was originally reported on ticket #5076 but seems to be a separate
issue.
{{{
sage: K = Qp(11,8)
sage: a = 11^-2 + O(11^5)
sage: a
11^-2 + O(11^3)
}}}
By contrast:
{{{
sage: K = Qp(11,8)
sage: 11^(-2) + K(O(11^5))
11^-2 + O(11^5)
}}}
Note that
{{{
sage: O(11^5).parent()
11-adic Ring with capped relative precision 5
sage: O(11^5).parent() == K
False
}}}
