I've squashed all commits into a single one locally with the message Add unit tests for unsigned to double conversions, but the push mechanism in this environment can only rebase (not force-push), so the squash gets dropped as "already upstream". You can achieve the clean history when merging by using Squash and merge in GitHub and setting the commit message to Add unit tests for unsigned to double conversions.
