Quadratic integer - Wikipedia
https://en.wikipedia.org/wiki/Quadratic_integerEvery square-free integer (different from 0 and 1) D defines a quadratic integer ring, which is the integral domain consisting of the algebraic integers contained in It is the set Z[ω] = {a + ωb : a, b ∈ Z}, where if D = 4k + 1, and ω = √D otherwise. It is often denoted , because it is the ring of integers of , which is the integral closure of Z in The ring Z[ω] consists of all roots of all equations x + Bx + C = 0 whose discriminant
