All,
Could anybody in/confirm the following result ? (scipy 0.8.0.dev5845),

 >>> import scipy.stats.distributions as dist
 >>> dist.gamma(4.).cdf(dist.gamma(4.).ppf(0.25))
0.0

I would have expected 0.25, of course. The pb seems to be
 >>> dist.gamma(4.).ppf(0.25)
0.0
when R gives 2.53532

Thx in advance for any help/comments
P.
