I understand, though consider floating point numbers don't stop at the first fractionary digit; actually the 5 that you'll arbitrarily round up (or down) will be far smaller for this to matter much. You can rely on having 16-17 decimal digits at the very least, and we can consider 1 million accounts will have an average of 5 digit accounts. This will mean there'll be at least 10 fractional digits, and you lose or win (if a bank or employer, win) just 1E-10 * 1E-1 * 1E+6 = 1E-5 dollars. Not even Scrooge would care for that.
