Beschreibung

Die Funktion greaterThanOrEqual vergleicht zwei Ausdrücke der Größe nach miteinander und gibt einen Wahrheitswert zurück, abhängig davon, ob der linksstehende Ausdruck größer-gleich dem rechtsstehenden Ausdruck ist.

Syntax

a >= b
greaterThanOrEqual(a,b)

Parameter

Return Value

  • Gibt einen Boolean zurück.
    Wenn der linke Ausdruck größer-gleich dem rechten Ausdruck ist, wird true zurückgegeben, andernfalls false.

Beispiele

6 >= 3    --> returns true

3 >= 3    --> returns true

greaterThanOrEqual(-1, 2)    --> returns false
