It can be very useful to have a base 10 exponent representation 
in certain situations where you need to have the exact same 
results in two systems (like a third party ERP server versus a 
client side application). Base 2 exponents are tricky (incorrect) 
when you read ascii.

E.g. I have resorted to using Decimal in Python just to avoid the 
weird round off issues when calculating prices where the price is 
given in fractions of the order unit.

Perhaps a marginal problem, but could be important for some 
serious application areas where you need to integrate D with 
existing systems (for which you don't have the source code).
