Changes (by vdelecroix):
* status: needs_review => needs_work
Comment:
- `The integral is always chosen so the constant term is 0.` -> `... so
that ...`
- inconsistency between dense and sparse
{{{
sage: R.<x> = PolynomialRing(Zmod(4), sparse=False)
sage: p = x**4 + 1
sage: p.integral()
x^5 + x
sage: R.<x> = PolynomialRing(Zmod(4), sparse=True)
sage: p = x**4 + 1
sage: p.integral()
Traceback (most recent call last):
...
TypeError: self must be an integral domain.
