GreaterThanOrEqual

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

• a - Gleitkommazahl
• b - Gleitkommazahl

Return Value

• Gibt einen Boolean zurück.

  Wenn der linke Ausdruck größer-gleich dem rechten Ausdruck ist, wird true zurückgegeben, andernfalls false.

Beispiele

<math>6 >= 3</math>    --> returns true

<math>3 >= 3</math>    --> returns true

<math>-1 >= 2</math>    --> returns false
