[Numpy-discussion] irfft, odd size input and truncation

Hi, While looking at improving numpy.fft, I encountered some issue with the definition of irfft for odd-size input. The docstring says that irfft(x, n) when n < x.size truncate the high frequencies of x, but it seems this is ambiguous for odd-size x and even n ? In particular, I can't manage to emulate irfft with ifft in that case. cheers, David
