            <title>[SERVER-39336] In order to be schema friendly, $mod output should be based only on input types, not values</title>
                <link>https://jira.mongodb.org/browse/SERVER-39336</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;$mod has a special condition if the right-hand-side is of non-integral type but of integral value.&lt;br/&gt;
&lt;a href=&quot;https://github.com/mongodb/mongo/blob/8387824b3ac937b0489fcb94c590cc663b47348c/src/mongo/db/pipeline/expression.cpp#L2528&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/mongodb/mongo/blob/8387824b3ac937b0489fcb94c590cc663b47348c/src/mongo/db/pipeline/expression.cpp#L2528&lt;/a&gt;&lt;br/&gt;
We should eliminate this condition from the conditional so that the output type of an arithmetic expression is based only on input types, not values. This has two benefits:&lt;br/&gt;
It causes a pipeline to output documents that are closer to a fixed schema.&lt;br/&gt;
Non-deterministicly-ordered input to grouping stages will no longer cause output of arbitrary type. This will eliminate the linked agg fuzzer issue.&lt;/p&gt;</description>

                            <customfieldvalue>The type of the result of a $mod expression is now determined solely from the input types; the exact input _value_ will no longer lead to a narrower result type.&lt;br/&gt;
&lt;br/&gt;
E.g., Previously  {{$mod: [2, 1.1]}} would result in a double result, but {{$mod: [2, 1.0]}}, would result in a integer, as the rhs _happens_ to be convertible to an int without rounding error despite being of double type.&lt;br/&gt;
&lt;br/&gt;
Now, the result type will always be the wider of the two input types.&lt;br/&gt;
&lt;br/&gt;
If the existing behaviour was relied upon, users may now find that code expecting an int instead of a long or double needs to be updated to expect the appropriate type result - or to provide arguments as ints if applicable.</customfieldvalue>
