A newbe question about 1000 digit math



Is there a way to display 1/7 to 100 digits or more?
Or any other math answer.

I am an octave user and I teach Math at College level.
We use Octave for all our control theory (Laplace and Z space) but I am 
trying to learn Maxima so I can get my students to use it for symbolic 
math manipulations.
So far (1 day) I have got the batch files to work and can use diff and 
integrate etc. to work.

Thanks for a nice program.
