-# $exp
-
-New from version 4.0
-
-The `$exp` operator in Amazon DocumentDB allows you to raise the constant e to a given number.
-
-**Parameters**
-
-  * `expression`: The expression to evaluate. This can be any valid aggregation expression, including field references, arithmetic operations, and other aggregation stages.
-
-
-
-
-## Example (MongoDB Shell)
-
-The following example demonstrates the use of the `$exp` operator to find all documents where the `quantity` field is greater than the `price` field.
-
-**Create sample documents**
-    
-    
-    db.items.insertMany([
-      { item: "canvas", quantity: 4 },
-      { item: "journal", quantity: 2 }
-    ]);
-
-**Query example**
-    
-    
-    db.items.aggregate([
-      { $project: {
-        "quantityRaised": {$exp: "$quantity"}}
-      }
-    ]);
-
-**Output**
-    
-    
-    [
-      {
-        _id: ObjectId('6920b785311cf98b79d2950d'),
-        quantityRaised: 54.598150033144236
-      },
-      {
-        _id: ObjectId('6920b785311cf98b79d2950e'),
-        quantityRaised: 7.38905609893065
-      }
-    ]
