bug #58068: gsl_sf_bessel_Jnu docs lacking important domain information

Submitter:  Jackson Vanover <jacksonvanover>
Submitted:  Sat 28 Mar 2020 05:30:16 PM UTC
 
Category:  Documentation Severity:  3 - Normal
Operating System:  Ubuntu 18.04 Status:  None
Assigned to:  None Open/Closed:  Open
Release:  2.6

Sat 28 Mar 2020 05:30:16 PM UTC, original submission:  

Using version 2.6 of GSL from ftp://ftp.gnu.org/gnu/gsl/gsl-2.6.tar.gz

OS is Ubuntu 18.04.2 LTS

Hardware is a Dell workstation with a 3.60 GHz Intel i7-4790 and 32 GB
of RAM

Compiler is gcc 7.4.0 with the -w option

The GSL documentation makes no mention of any domain restrictions for
the gsl_sf_bessel_Jnu function, but when the second argument is
negative or zero, the error handler is invoked with a domain error. The docs
should reflect this by mentioning that the second argument must be positive.

#include <gsl/gsl_sf.h>
#include <stdio.h>
#include <gsl/gsl_math.h>
#include <float.h>

int main (void){
        double out;
        out = gsl_sf_bessel_Jnu(1, -1);

        printf("%.*f\n", DBL_DIG-1, out);
        printf("%.21e\n", out);
        return 0;
}
