e/Quater-imaginary base

Information
has gloss	eng: The quater-imaginary numeral system was first proposed by Donald Knuth in 1955, in a submission to a high-school science talent search. It is a non-standard positional numeral system which uses the imaginary number 2i as its base. It is able to represent every complex number using only the digits 0, 1, 2, and 3. (Numbers less than zero, which are ordinarily represented with a minus sign, are representable as digit strings in quater-imaginary; for example, the number −1 is represented as "103" in quater-imaginary notation.)

Cest un système de numération positionnel non-standard qui utilise le nombre imaginaire 2i\, pour base. Par analogie avec le système de numération quaternaire, il est capable de représenter chaque nombre complexe en utilisant seulement les chiffres 0, 1, 2 et 3, sans un signe.
