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
 or(x,y)

Parameter

Return Value

  • Gibt einen Boolean zurück.

Beispiele

1 || 1    --> returns true

0 || 1    --> returns true

1 || 0    --> returns true

0 || 0    --> returns false

(2+4==6) || (3+3==6)    --> returns true

Hinweise

  • erwartet zwei boolsche Ausdrücke
