Octave: Precise value in Decimal or Continuous Fraction for 729 / 4^3

Question

I get the approximation:

>> 729 / 4^3 
11.391

Is there some function to get more precise approximation?

Answer 1

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.
