On my Linux/586 machine, I get
> ifft(fft([1 1 0 0 1]))
ans =
1.0000e+00 1.0000e+00 -1.4682e-08 -1.4682e-08 1.0000e+00
This is only single precision accurate. Unfortunately the other
machines I have access to have the same architecture and use the
same binary and not surprisingly gives the same result.
What happens on your machine?
Octave, version 2.0.8 (alpha-dec-osf4.0).
