|nfrootsof1(bnf) vs. bnf.tu|
Hello pari-users,I somehow always assumed that the unit given by nfrootsof1(bnf) would be the same as bnf.tu
I now realize that this assumption is false. However, it does seem that PARI-2.9.1 has made this assumption much more false than it was in PARI-2.8.0.
With PARI-2.9.1 the result of nfrootsof1() seems random (it can be different with every call). With PARI-2.8.0, I could only find counter-examples to nfrootsof1(bnf) == bnf.tu in degree >= 16.
Do you consider this a bug? It would be convenient if nfrootsof1(bnf) would be the same as bnf.tu, but I don't know how much effort it would take to enforce that.
