I think that precision when dealing with money is very important (more important than speed). Money values should be handled internally as an string of decimal digits, as in COBOL. Very big numbers are frequent when you deal with money : $1,000,000,000 converted to a weakest currency can have 5 or 6 signficant digits. They is other problems when calculating in base 2 instead of base 10 : the numbers that have an infinite number of digite after the point are not the same. It has an impact on rounded values.
