Binary numeral system/fr

Deutsch · English · Français · Português · Suomi · Русский

La représentation binaire d'un nombre n'utilise que les chiffres 0 et 1. Le système en base 2 est la base des systèmes numériques. Le plus petit élément binaire est appelé un bit (contraction de l'anglais BInary digiT).

Dans un source Free Pascal, un littéral binaire est spécifié en le faisant précéder par signe pourcent (%).
