On my machine (Sparc 10, solaris 2.4) and with Octave 2.0.9,
I get:
echos{bgard}41: octave
Octave, version 2.0.9 (sparc-sun-solaris2.4).

octave:1> ifft(fft([1 1 0 0 1]))
ans =
1.0000e+00 1.0000e+00 7.3275e-16 7.3275e-16 1.0000e+00
octave:2>
So I get double precision accuracy on my version of Octave.
My version is not the lastest (it is more recent then my printed
version of the manual which is version 1.0 Feb 1994).
