[Bug-gsl] Bug in gsl_sf_hyperg_U

[Kovid Goyal]

Hi,

The Hyper geometric U function gsl_sf_hyperg_U gives incorrect results on a
linux x86 machine (gsl version 1.12).

For example:

gsl_sf_hyperg_U(-2.0, 0.5, 1.13) gives 0.75 which is the wrong value (it is the
expected value for x = 0.

Running gsl_sf_hyperg_U(-2.0, 0.5, 0) gives a domain error.

I'm not subscribed to the list, so please CC replies to address@hidden

Thanks,

Kovid.
