Gaussian integer : ウィキペディア英語版 | Gaussian integer In number theory, a Gaussian integer is a complex number whose real and imaginary parts are both integers. The Gaussian integers, with ordinary addition and multiplication of complex numbers, form an integral domain, usually written as . This integral domain is a particular case of a commutative ring of quadratic integers. It does not have a total ordering that respects arithmetic. ==Formal definition== Formally, the Gaussian integers are the set :〔 Note that when they are considered within the complex plane the Gaussian integers may be seen to constitute the -dimensional integer lattice.
