(A) When a question is put by the Mayor, every member present must vote unless excused by the Council, but if interested the member shall not vote. In doubtful cases, the Mayor may direct or any member call for a division. It is assumed that every vote is unanimous and it must be recorded accordingly unless a poll of the members is called upon a requisition of the Mayor or any member, in which case the names of the members voting are required to be recorded in the minutes and whether each has voted yea or nay.
(B) Votes of the members on any business coming before the Council may be by voice vote, standing vote, or in such other manner of voting as may signify the intention of the members.
