What problem are you facing?

Spec tests say -0 should be serialized to EJSON differently from +0:

https://github.com/mongodb/specifications/blob/bafb024be8202b1676a3c6632e8a3eb9cf36209b/source/bson-corpus/tests/double.json#L42-L53

This isn’t something that’s easily fixable for the relaxed EJSON, since JSON.stringify(-0) === '0', but should be fixable for canonical EJSON.

(This only occurs with -0 JS numbers, not Double(-0) bson objects.)

What driver and relevant dependency versions are you using?

Latest js-bson (4.6.5).

Steps to reproduce?

> EJSON.stringify({ neg: -0, pos: 0 }, { relaxed: false })
'{"neg":{"$numberInt":"0"},"pos":{"$numberInt":"0"}}'
