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
decimal.
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.
"binary"...

I don't see this page as a need to 'return to decimal hardware' so much

These are turing-derived machines, after all, and can do decimal
arithmetic when we want them to.

"Black holes are where God is dividing by zero"
There are
SOME people (I am NOT one) who actually feel that
DECIMAL is the right way to go in computers!
If the computers are doing my bank statements, then yes, I am one of
them.
