#1768: hyperu scipy vs. mpmath
------------------------------+---------------------------------------------
 Reporter:  unknown (google)  |       Owner:  pv         
     Type:  defect            |      Status:  new        
 Priority:  low               |   Milestone:  Unscheduled
Component:  scipy.special     |     Version:  0.10.1     
 Keywords:  hyperu            |  
------------------------------+---------------------------------------------
 >>> scipy.special.hyperu(1, 1.5, 20.2)
 0.04836079226599823
 >>> mpmath.hyperu(1, 1.5, 20.2)
 mpf('0.048360918656699191')

 This is like a 1e-6 relative error.  I don't know how good the scipy
 special functions are supposed to be, especially the hypergeometric ones,
 so I am putting this ticket at low priority because the scipy function
 gives an answer that is at least not nan or segfault.
