2 basic calc questions

[Ryan Moszynski]

1) how do I get calc to display answers as a decimal with all trailing
digits until there are repeated zeros?

for example, I would like to display the result of
.5 * .09^2
as
0.00405

2) how do i get the calc trail window to scroll automatically so that
the bottom of the calc trail, with most recent calculation is always
shown?

thanks,

Ryan M
