This line of code is intended to implicitly convert double BSONElements to int when the conversion is exact:

https://github.com/mongodb/mongo/blob/1bdff76322b144ef27060fe79324fe3cce4bb17a/src/mongo/db/matcher/expression_parser.cpp#L1738

However, the call to `BSONElement::numberInt()` can fail when the number would overflow the int type. Additional checking is necessary to ensure that failure doesn't occur.
