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

Parameter

  • a - double
  • b - double

Return Value

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

Beispiele

    --> returns true
    --> returns true
    --> returns false
