From version 28, RoundDown is kept for backward compatibility. This function has been replaced with RoundFloor.
Returns:
  • the numeric value rounded down to the nearest integer.
  • the duration rounded down to the nearest interval.
  • the date and time rounded down to the nearest interval.
Example
ResArrondi = RoundFloor(-16.238167,2) // Renvoie -16.24
ResArrondi = RoundFloor(3.9) // Renvoie 3 (pas de décimales)
ResArrondi = RoundFloor(3.999,2) // Renvoie 3.99
ResArrondi = RoundFloor(1.9) // Renvoie 1
ResArrondi = RoundFloor(-1.9) // Renvoie -2
// Arrondi d'une Durée
ResArrondiDurée is Duration
ResArrondiDurée = RoundFloor(13 min, 5 min) // Renvoie 10 min (0001000000)
// La durée est découpée en périodes de 5 minutes. 
// Le résultat correspond au début de la période qui contient la durée 13 min.
// Arrondi d'une DateHeure
dhMonDateHeure is DateTime = "202211041524"
Trace("dhMonDateHeure : " + dhMonDateHeure)
Trace("ArrondiInférieur : " + RoundFloor(dhMonDateHeure, 7 min)) 
// Affiche 20221104152400000

// La journée est découpée en périodes de 7 min. 
// Dans cet exemple, la variable dhMonDateHeure correspond à l'arrondi inférieur
