Computer assignment 1

[E Huang]

Hello,

I need some help for assignment 1, and I believe that everybody will run into
this problem (unless I am doing something wrong).

My three methods for calculating the future value give exactly the same
results. This is because Matlab works always to double precision, thus
nullifying the intended demonstration of roundoff error.

What should I do?
a) Leave it as it is.
b) find a way to 'fake' a poorer precision.

If b), then how can this be done? I suppose using the round() function on
critical calculations can work, but is there a better way?
