Use $toDouble in Updates
If we need to update existing documents and insert float values, use the $toDouble operator to ensure the values are treated as floats.
db.products.updateOne(
{ "_id": 1 },
{ "$set": { "price": { "$toDouble": "40" } } }
);
Output:
Explanation: This query updates the document with the _id
of 1 in the products
collection, setting the price
field to the double value of 40. The $toDouble
aggregation operator is used to explicitly convert the string “40” to a double value before setting it as the new value for the price
field.
