rng question

["Jari Häkkinen" <jari@chiralcomp.com>]

Hi all,

I have question about the random number generator features and 
documentation.

According to the documentation gsl_rng_max(rng_ returns the maximum 
random number the underlying rng can give, and 
gsl_rng_uniform_int(rng,gsl_rng_max(rng)) will return 
[0,gsl_rng_max(rng)-1]. This will not give the maximum number from the 
underlying generator, so I tried 
gsl_rng_uniform_int(rng,gsl_rng_max(rng)+1) but this call does not 
return (since the second argument becomes 0).

Shouldn't this case be covered by GSL? Either by returning a error code 
or maybe setting the upper bound to gsl_rng_max(rng) when a 0 second 
argumnet is given? At least, I think this case should be covered in the 
documentation.


Cheers,

Jari
