Summary

Entire documentation page for the $mod operator was removed, including all content, examples, and code samples

Security assessment

This change removes documentation for a mathematical operator ($mod) in Amazon DocumentDB. There is no evidence in the diff that this removal is related to a security vulnerability or incident. The removed content appears to be standard documentation for a database operator with example usage, not security-related content. The change appears to be routine documentation maintenance or restructuring.

-# $mod
-
-The `$mod` operator is an arithmetic operator that performs a modulo operation on a number. It returns the remainder of dividing one number by another. This operator is commonly used to determine if a number is odd or even, or to distribute items into a finite number of groups.
-
-**Parameters**
-
-  * `expression1`: The dividend expression.
-
-  * `expression2`: The divisor expression.
-

-
-## Example (MongoDB Shell)
-
-This example demonstrates how to use the `$mod` operator to determine the number of leftover widgets when shipping in packages of 100.
-
-**Create sample documents**
-    
-    
-    db.widgets.insertMany([
-      { "_id" : 1, "widget" : "A", "count" : 80372 },
-      { "_id" : 2, "widget" : "B", "count" : 409282 },
-      { "_id" : 3, "widget" : "C", "count" : 60739 }
-    ])
-
-**Query example**
-    
-    
-    db.widgets.aggregate([
-      { $addFields: { leftOver: { $mod: [ "$count", 100 ] } } }
-    ])
-
-**Output**
-    
-    
-    [
-      { "_id" : 1, "widget" : "A", "count" : 80372, "leftOver" : 72 },
-      { "_id" : 2, "widget" : "B", "count" : 409282, "leftOver" : 82 },
-      { "_id" : 3, "widget" : "C", "count" : 60739, "leftOver" : 39 }
-    ]
-
-The output shows the remainder of the `count` divided by 100 for each document, which represents the number of leftover widgets when shipping in packages of 100.
