here's an explanation of the changes in `BigDecimal`.

Rather than keeping track of a local `int scl` (scale) and a local `long exp` 
(exponent), the change only keeps track of a `long scl`, adapting it 
accordingly. It checks the range of `scl` before initializing the fields. This 
makes for a simpler code.

In addition, I couldn't resist changing C-style arrays to Java style over the 
whole class.
