Beschreibung

Die Funktion BooleanOr ("||") vergleicht zwei Aussagen auf true oder false. Es wird nur dann false zurückgegeben, wenn beide Aussagen false sind.

Syntax

x || y

Parameter

• x - Boolean
• y - Boolean

Return Value

• Gibt einen Boolean zurück.

Beispiele

 1 || 1    --> True
 0 || 1    --> True
 1 || 0    --> True
 0 || 0    --> False

 (2+4==6) || (3+3==6)    --> True
