#1212: Single precision FFT insufficiently accurate.
 Reporter:  rgommers       |       Owner:  somebody
     Type:  defect         |      Status:  new     
 Priority:  normal         |   Milestone:  0.8.0   
Component:  scipy.fftpack  |     Version:  0.7.0   
 Keywords:                 |  
 For some input sizes (factoring into large prime numbers) the accuracy of
 single precision fft is not good enough. For details see

 In the 0.8.x branch the problem is circumvented by switching to double
 precision except for sizes that are composites of factors 2, 3 or 5.
