Boolean

In logic and in computer programming, a Boolean is a binary variable with two possible statuses: "true" or "false" ("vrai" or "faux" in French).

The values accepted for the true/false status are the following (non-case-sensitive):

• 0 (zero) = false and any other numerical value = true
• True / False or T / F
• Vrai / Faux or V / F
• Yes / No or Y / N
• Oui / Non or O / N
