Hello,
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.
This is indeed a bug. Sage calls the wrong PARI function for this
conversion: it should
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
