Beschreibung
Die Funktion BooleanAnd ("&&") aus der Bool'schen Algebra vergleicht zwei Aussagen auf "true" oder "false". Der Ausdruck x && y gibt true zurück, wenn x und y beide true sind, ansonsten wird immer false zurückgegeben.
Syntax
x && y
Parameter
- x - boolean
- y - boolean
Return Value
- Gibt einen Boolean zurück.
Beispiele
1 && 1 --> true 0 && 1 --> false 1 && 0 --> false 0 && 0 --> false
(2+4==6) && (3+3==6) --> true
