Definition(s)

  • In number theory, quadratic integers are a generalization of the usual integers to quadratic fields. Quadratic integers are algebraic integers of degree two, that is, solutions of equations of the form

    x2 + bx + c = 0

    with b and c (usual) integers. When algebraic integers are considered, the usual integers are often called rational integers.
