AWS documentdb documentation change

Service: documentdb · 2026-03-28 · Documentation low

File: documentdb/latest/developerguide/toDouble.md

Summary

Entire documentation page for the $toDouble operator in Amazon DocumentDB has been removed, including all examples, code samples, and usage instructions.

Security assessment

The change removes documentation for a MongoDB aggregation operator ($toDouble) but shows no evidence of addressing a security vulnerability, weakness, or incident. The removed content was purely functional documentation about type conversion. The examples included TLS connection parameters, but their removal doesn't indicate a security fix.

-# $toDouble
-
-New from version 4.0
-
-The `$toDouble` operator in Amazon DocumentDB is used to convert a value to a double-precision 64-bit floating-point number. This can be useful when you need to perform arithmetic operations on values that are not originally in a numeric format.
-
-**Parameters**
-
-`<expression>`: The expression to convert to a double value. This can be any valid expression that resolves to a numeric, string, or boolean value.
-
-## Example (MongoDB Shell)
-
-This example demonstrates how to use the `$toDouble` operator to convert a string value to a numeric value for the purpose of performing a mathematical calculation.
-
-**Create sample documents**
-    
-    
-    db.numbers.insertMany([
-      { _id: 1, value: "10.5" },
-      { _id: 2, value: "20.25" },
-      { _id: 3, value: "7" }
-    ])
-
-**Query example**
-    
-    
-    db.numbers.aggregate([
-      {
-        $project: {
-          _id: 1,
-          value: 1,
-          double_value: { $toDouble: "$value" },
-          double_plus_five: { $add: [{ $toDouble: "$value" }, 5] }
-        }
-      }
-    ])
-
-**Output**
-    
-    
-    [
-      { "_id" : 1, "value" : "10.5", "double_value" : 10.5, "double_plus_five" : 15.5 },
-      { "_id" : 2, "value" : "20.25", "double_value" : 20.25, "double_plus_five" : 25.25 },
-      { "_id" : 3, "value" : "7", "double_value" : 7.0, "double_plus_five" : 12.0 }
