#5946: bug in content for p-adic polynomials
------------------------+---------------------------------------------------
Reporter: AlexGhitza | Owner: roed
Type: defect | Status: new
Priority: minor | Milestone: sage-4.0
Component: padics | Keywords: content p-adic polynomial
------------------------+---------------------------------------------------
We ran into this at #5921. There are two separate issues: polynomials
with coefficients in a p-adic field should not have a {{{content()}}}
method, since it doesn't make sense (the same way that having a
{{{content()}}} method for polynomials with rational coefficients doesn't
make sense).
The second issue is with the {{{content()}}} method for polynomials with
coefficients in p-adic rings. Here's an example:
{{{
sage: P.<x> = ZZ[]
sage: f = x + 2
sage: f.content()
1
sage: fp = f.change_ring(pAdicRing(2, 10))
sage: fp
(1 + O(2^10))*x + (2 + O(2^11))
sage: fp.content()
0
}}}
