Fourier[] malfunction?

  • Subject: [mg2933] Fourier[] malfunction?

Is my Fourier function malfunctioning?

In:
Fourier[{I,2,3,4}]
Out:
Fourier[{I, 2, 3, 4}]

In:
N[Fourier[{1,2,3,4}]]
Out:
{5. + 0. I, -1. - 1. I, -1. + 0. I, -1. + 1. I}

Should I have to use N[Fourier[list]] to get an appropriate response?
Wolfram's book (*Mathematica: A System for Doing Mathematics by
Computer*) seems to indicate that there is a malfunction here. Any
ideas?

Thanks,
Brett Shoelson
