Well I would be VERY happy if I could get an API that supports currency operations according to local rules and regulations. For instance, it should use "Argentina Rounding" and 2 decimal precision if you are making operations in an Argentina culture and the operations should follow the other rules and regulations that apply to Argentina. But I could settle for less. ;) Maybe I could settle for an API that implements various rounding schemes. Swiss rounding, Argentina rounding, bankers rounding etc. :) The currency precision is already available in the framework today using the CultureInfo class although I'm not sure which standard it follows.
