MongoDB divide aggregation operator?
You can use aggregate framework for this. Let us first create a collection with documents −
>db.aggregationOperatorDemo.insertOne({"FirstValue":392883,"SecondValue":10000000000});
{
"acknowledged" : true,
"insertedId" : ObjectId("5cd541452cba06f46efe9f01")
}Following is the query to display all documents from a collection with the help of find() method −
> db.aggregationOperatorDemo.find().pretty();
This will produce the following output −
{
"_id" : ObjectId("5cd541452cba06f46efe9f01"),
"FirstValue" : 392883,
"SecondValue" : 10000000000
}Following is the query to use divide aggregation operator −
> db.aggregationOperatorDemo.aggregate([
... { "$project": { "Value": { "$divide": ["$FirstValue", "$SecondValue"] } } }
... ]);This will produce the following output −
{ "_id" : ObjectId("5cd541452cba06f46efe9f01"), "Value" : 0.0000392883 }
