Definition (Gaussian integers) A Gaussian integer is a number of the form a + bi where a and b are two integers and i is an imaginary number such that i 2 = −1. The set of all Gaussian integers is usually noted Z [i]. Golden rule Addition and multiplication in the set Z [i] follow the same rules as addition and multiplication of integers but “real parts” and “imaginary parts” cannot be mixed up in addition.
