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
