why google finance puts to two decimal places for the trading volumes?

many brokerages offer automatic dividend reinvestment. it is very infrequent that these dividends are exactly a whole share. so, if you have signed up for automatic dividend reinvestment, many brokerages will reinvest your dividends and assign to you a fractional share. i can't speak for how these shares work with regards to voting, but i can say that the value of these fractional holdings does change with stock price as if one genuinely could hold a fraction of a share.
