Explicitly Insert Float Values

When inserting documents into MongoDB, explicitly define float values for float fields. If we have integer values, convert them to floats before insertion.

db.products.insertOne({
"name": "Product 3",
"price": 30.0 // Insert float value
});

Output:

Explanation: This query inserts a new document into the products collection with the name "Product 3" and a price of 30.0. The price is inserted as a float value, which MongoDB will internally store as a 64-bit floating-point number.

How to Inserts float When trying to Insert Integer in MongoDB

MongoDB, a popular NoSQL database, provides flexibility in defining data types for fields within documents. However, when attempting to insert integer values into fields defined as floats, unexpected behavior may occur.
