Beschreibung
Die Funktion equalssemisem vergleicht zwei rationale Zahlen miteinander auf ihre Gleichheit. Die Funktion erwartet zwei Zahlen und gibt einen Boolean zurück.
Syntax
equalsemisem(String zahl1, String zahl2)
Parameter
- zahl1 - erste zu vergleichende rationale Zahl
- zahl2 - zweite zu vergleichende rationale Zahl
Return Value
- Gibt einen Boolean zurück
Beispiele
Standardfälle
equalssemisem('7.3','7.3') --> returns true equalssemisem('7.3','6.2') --> returns false
Benutzung von Variablen
equalssemisem('[pos=1]','2.4') equalssemisem('4.1','[var=a]') equalssemisem('[var=a]','[pos=2]')
