Use Case

As a Node.js BSON library user
I want decode 64 bit floats on big-endian machines
So that I obtain the correct data from BSON

Regression introduced in: https://github.com/mongodb/js-bson/pull/649

User Impact

• Big-endian systems will parse the bytes in reverse order

Dependencies

• NumberUtils.get/setFloat64LE

Unknowns

• Can we enable testing easily?

Acceptance Criteria

Implementation Requirements

• Detect endianness and flip the offset logic inside the float parsing and serializing methods

Testing Requirements

• Manual testing if adding a new evergreen host proves difficult. Follow up with adding CI testing.

Documentation Requirements

• None

Follow Up Requirements

• None
