            <title>[SERVER-51455] Fix SBE hashValue for the double type values</title>
                <link>https://jira.mongodb.org/browse/SERVER-51455</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;hashValue tries to hash doubles as integers so that e.g. 2.0 (double) and 2 (integer) hash to the same value. This is important in order to keep the assumption v1 == v2 =&amp;gt; hash(v1) == hash(v2).&lt;/p&gt;

&lt;p&gt;We do it by simply casting doubles to integers and then hashing the integers. Unfortunately, ubsan is unhappy about casting weird values not representable as integers (i.e. NaN, Inf, too big).&#160;&lt;/p&gt;

&lt;p&gt;The fix is obvious.&lt;/p&gt;</description>
