Roman Leschinskiy tells me that there are C (or C++?) libraries for locale-specific money handling, where given precisions are mandated in particular countries, below which you must round. Perhaps we should have a binding to this.
IIRC, the rules in the EU were that operations on money have to be done with 3 decimal digits and then rounded to 2. That is, 0.01 / 2 = 0.01 (0.005 rounded to 2 decimal digits). I may be mistaken, though. What I'm fairly sure of is that required precision and rounding policies differ from country to country. Getting it right is *much* harder than it looks.
