[Help-gsl] Recourse, overflowing lngamma

[Marc]

Hello,

I've been using GSL for an intensive numerical calculation involving large
numbers. I rely on gsl_sf_lngamma, however it overflows at points of my
program where the argument is large.

What options are available to deal with this difficulty considering that I
do need the values of the lngamma for very large argument?

Thanks
