-------------------------------------

Not even double as it suffers from floating point problem. See 
http://stackoverflow.com/q/3730019/696632.

> Uses a Float type to represent dollar amounts.  This is a bad idea--floating 
> point values are not large enough to represent larger transactions and this 
> could teach developers bad habits, especially in enterprise environments.
> At the least you should use the Double class in your example.
