> Storing money in floating point is fine. Just round to the nearest atomic unit when displaying.
Well, it's not just a display issue. In accounting, associativity and commutativity are important. People do care that `a + b + c - a == c + b` should evaluate to “true”.
It appears you did not see the critical point in the above comment. "Performing arithmetic operations against money in floating point is the dangerous part, as error can accumulate beyond an atomic unit."
