Hello,
I have a questionnaire with 3 questions of type number: question1, question2 and question3.
On the questionnaire I setup a trigger which sets question3=question2/question1 once question1 and question2 are not empty.
I'd like to display the value of question3 with maximum 2 decimal digits. Is it possible?

Hello,
You need to use the displayStyle
and maximumFractionDigits
options for the expression:
JavaScript{
"pages": [
{
"name": "page1",
"elements": [
{
"type": "text",
"name": "question1",
"inputType": "number"
},
{
"type": "text",
"name": "question2",
"inputType": "number"
},
{
"type": "expression",
"name": "question3",
"expression": "iif({question1}, {question2}/{question1}, 0)",
"displayStyle": "decimal",
"maximumFractionDigits": 2
}
]
}
]
}
Thanks, Serge
