#748: Ifft pads incorrectly
 Reporter:  stefan     |        Owner:  somebody
     Type:  defect     |       Status:  new     
 Priority:  normal     |    Milestone:  1.1.0   
Component:  numpy.fft  |      Version:  devel   
 Severity:  major      |   Resolution:

Comment (by charris):

 Let me add that if you are padding for interpolation before doing an
 irfft, then you should pad at the end and halve the value at the Nyquist.
 This is equivalent to the middle padding above. I'm not familiar with what
 the other fft's do, so can't comment on the padding.
