Re: Divisors bug in GP |

It is documented (in 2.2.8, CHANGES-1.951 at least) : (11:01) gp > ??divisors divisors(x): creates a row vector whose components are the positive divisors of the integer x in increasing order. The factorization of x (as output by factor) can be used instead. The library syntax is divisors(x). > Anyway, it seems to 'break' its parameter. Right. I have fixed the problem in CVS.
