To be honest, I never understood well how this bitset operator works.
What I see is that "2 << -i" gives the same result than "2^(-i+1)".
I should have write "2 << (-i + 1)" instead of "/2"...

Besides this, I would like to remove these ugly "if"s I added yesterday,
but I don't see a better human-readable solution.
