proof
parameter
---------------------------------+------------------------------------------
Reporter: malb | Owner: malb
Type: defect | Status: new
Priority: major | Milestone: sage-3.4.2
Component: commutative algebra | Keywords: singular, factor
---------------------------------+------------------------------------------
Comment(by AlexGhitza):
Two issues:
* in the first patch, "proofably" should be "provably"
* I'm getting some slight numerical noise in the doctests from the second
patch:
