Like the fact that the IEEE representation of decimal fraction of 
terminating numbers much small than the operational limits of the 
machine is never the less inaccurate unless it happens to have a 5 in 
it's prime factorization?

It seems to be a monument to stupidity.

It can't accurately represent 0.1. Why is this considered useful?

Allow me to change my "bug report" to a query: Is there a bignum package 
for emacs that supercedes all the regular operators so the if I add a 
bunch of prices, I don't get strange numbers?
