#5496: fix bugs in is_prime (EASY)
---------------------------+------------------------------------------------
Reporter: was | Owner: was
Type: defect | Status: new
Priority: major | Milestone: sage-3.4.1
Component: number theory | Keywords:
---------------------------+------------------------------------------------
This is not good:
{{{
sage: is_prime(GF(5)(3))
True
sage: is_prime(GF(5)(4))
False
}}}
The fix is to totally 100% rewrite is_prime in arith.py so that it first
calls x.is_prime() and if that isn't defined, then in some special cases
(e.g., python ints) converts to Integer and calls is_prime. Otherwise, it
raises a NotImplementedError.
