How do fractional cent dividends work?
In ETFs such as SPY, which represents a group of stocks, the dividends come from pooling the underlying dividends and comes to a long decimal (such as $1.383619 on 2019-09-20).
What is the official source to get the exact dividend amount? Different online sources state the same dividend rounded to fewer decimal points, so it is unclear what the exact amount is.
I imagine that if the dividend is for value X and you own Y shares, then you will receive X * Y where any rounding to the cent occurs after multiplication. And that the rounding can vary by broker (i.e. their rounding method, or not rounding at all if they let accounts hold fractional cents). Are those statements correct?
