Can you just put a comment above this that says that this is in little endian order?  That will make it easier if anyone tries to make big endian work, and need to grep for search for places to make needed changes.  A comment is cheap and can be so helpful here.

Thank you very much for the review. I also added another comment in another place that is "little-endian" specific.
