Génerer un nombre numérique aléatoire

Bonjour
Je voudrais savoir comment je peux generer un nombre de facon automatique dans SuSo

You cannot “generate” random numbers in your questionaire.
However, each interview gets a random number assigned during creation.
You can reference this number in your questionnaire expressions as:

Quest.IRnd()

It will return a single double precision number between 0 (included) and 1 (excluded).

There are several posts on this forum discussing techniques for using random numbers in interviews.
You’ll find lots of additional information.

Merci beaucoup cher @klaus
Maintenant, quelle est la syntaxe pour me permettre d’extraire un nombre de 4 chiffres aléatoire parmi les 16 générés précédemment
Merci bien

See the discussion here:

Say you want a number between 1 and 9999:

Then the expression

(long) Math.Floor(((decimal)Quest.IRnd())*(decimal)9999) + 1

would return it.

You can also substitute 9999 by the variable of a numeric question, say, numberRooms.
The expression would then randomly select the number of one of the rooms.
