Scheme 48 Eclipse IDE

Hello,

thanks for providing Scheme48. I use it to work trough the SICP and so 
far it works pretty well.

Two things concerning the Eclipse IDE:
1) Division results are represented as something like 23987732742983723 
/ 23048329048320843 instead of 123.456, which is very unreadable and 
requires you to copy and paste the values into a calculator
2) Typing a close parenthesis just before a close parenthesis should not 
create a new close parenthesis:
             (define (f a b) (* (square a) (square b)Z)) ; should not 
get a new ) when typing ) at location Z

Regards,
Alex
