# Octave: Precise value in Decimal or Continuous Fraction for 729 / 4^3 [closed]

I get the approximation:

``````>> 729 / 4^3
11.391
``````

Is there some function to get more precise approximation?

Update:

``````octave:1> 729/4^3
ans =  11.391
octave:2> format long
octave:3> 729/4^3
ans =  11.3906250000000
octave:4>
``````

Have you tried the "format long" command?

I'm installing octave right now. I used to use it and Matlab while I was in college.

So it is not possible to specify the accuracy, eg to 128 decimals? – Masi Oct 8 '09 at 22:38
