Having spent four and a half years running IT at the Philadelphia Federal
Reserve Bank and almost ten years responsible for Investment Quantitative
Analysis, Trust Systems and Automation Planning for a major regional bank
(now Wachovia) - I can assure you that banks do all their accounting in

Investment analysis, manket and economic models, arbitrage analysis,
regression analysis, etc. are done in floating point.

They really know the difference and when it's important do use decimal v.
