If I have a number(s) in an algebraic number field, and I want to check if it is an algebraic integers how do I do it in Pari/GP. Please help!

https://ask.sagemath.org/question/9174/algebraic-integer-parigp/?comment=19351#post-id-19351You can use that an algebraic number is integral iff its minimal polynomial has integer coefficients. I believe that PARI's minpoly should give you the minimal polynomial starting from a polmod object.Wed, 25 Jul 2012 02:04:25 -0500https://ask.sagemath.org/question/9174/algebraic-integer-parigp/?comment=19351#post-id-19351Comment by benjaminfjones for <p>in sage you check if an algebraic number is an algebraic integer with is_integral.

https://ask.sagemath.org/question/9174/algebraic-integer-parigp/?comment=19353#post-id-19353I would consult the PARI/GP manual.
