I don't remember the last time I owed π dollars to someone. Remember, you are starting with finite amounts (fractions of cents), not numbers like π.

There not always a potential for round-off to occur, when the system has bounds. When something is 1/3rd off, the discount will be rounded/ceiled/floored. Infinite precision is not needed.
