Octave doesn't really have a concept of significant figures. It uses
IEEE 754 doubles by default. There are other numeric types, but I
doubt they're the ones you want. You can change how many are in the
output with "format long" or "format short". Also look at this:

But if you need many arbitrary-precision calculations, Octave isn't
the tool for the job. Use Pari/GP or Maxima or even GAP instead.
