Beschreibung

Die Funktion IEEEremainder berechnet die Remainder-Operation auf zwei Argumente, wie es in dem IEEE 745 Standtard beschrieben ist [1]. Die Funktion erwartet zwei Zahlen und gibt das entsprechende Ergebnis zurück.

Syntax

IEEEremainder(float f1, float f2)

Parameter

  • f1 - Zähler
  • f2 - Nenner

Return Value

  • Gibt den Rest-Wert zurück, wenn f1 durch f2 geteilt wird

Beispiele

Standardfälle

IEEEremainder(4,2)   --> returns 0
IEEEremainder(3,2)   --> returns -1

Benutzung mit Variablen

IEEEremainder([pos=1],[pos=2])
IEEEremainder([var=a],[var=b])
