Hi Samuel, I guess t_INT is the 64-bit sign integer in the pari library, which is written in C. It means the positive size is 63 bits. The number 2^63 corresponds to -1 and pari raises an error. The following code works fine.
sage: p = previous_prime(2^64) sage: F.<x> = GF(p^2) sage: x * (2**63 - 1) Kind regards, Oleksandr On Saturday, July 26, 2014 5:39:42 AM UTC+2, Samuel Neves wrote: > > I seem to have run across a potential bug on Sage: > > p = previous_prime(2^64) >> F.<x> = GF(p^2) >> x * 2**63 >> >> > throws a "overflow in t_INT-->long assignment" exception creating the > element x * 2**63.
