-# $ln
-
-New from version 4.0.
-
-The `$ln` operator in Amazon DocumentDB calculates the natural logarithm (base e) of a specified number. It returns the logarithm of the number to the base e.
-
-**Parameters**
-
-  * `expression`: The number for which the natural logarithm will be calculated.
-
-
-
-
-## Example (MongoDB Shell)
-
-The following example demonstrates the usage of the `$log` operator to calculate the natural logarithm of a number.
-
-**Create sample documents**
-    
-    
-    db.numbers.insertMany([
-      { _id: 1, value: 10 },
-      { _id: 2, value: 100 },
-      { _id: 3, value: 1000 }
-    ]);
-
-**Query example**
-    
-    
-    db.numbers.aggregate([
-      { $project: {
-        _id: 1,
-        naturalLog: { $ln: "$value" }
-      }}
-    ]);
-
-**Output**
-    
-    
-    [
-      { "_id" : 1, "naturalLog" : 2.302585092994046 },
-      { "_id" : 2, "naturalLog" : 4.605170185988092 },
-      { "_id" : 3, "naturalLog" : 6.907755278982137 }
