The results are compiled over the "expressed suffrage", leaving aside the blank votes or the "null" votes: marking on the paper ballots, two ballots in the same envelope, not one of the official candidate ballots,... I have helped counting the ballots a few times over the years (this is always done by volunteer citizens), and I've seen it all.

But they are totalized locally and nationally.
Some graphs here :
Of those who voted, Macron won a majority : 54.7% / 38.8%, 6.5% respectively.

Some agitate for a significant blank vote
