Ballots that cannot unambiguously be assigned to a candidate are not considered invalid, but are assigned to all potentially intended candidates proportionally to the unambiguous votes each candidate has received. These so-called are rounded to the third decimal. For example, if "Yamada A" and "Yamada B" both stood in an election and there were 1500 unambiguous votes: 1000 for "Yamada A" and 500 for "Yamada B"; five ambiguous votes for "Yamada" would then count for Yamada A as 5×1000/1500=3.333 votes, and for Yamada B as 5×500/1500=1.667 votes.
