Description

Below fisher f quantile function call should return 'NaN' but it raises internal error:

SELECT madlib.fisher_f_quantile(                 
                '0.5'::double precision,    --p  
                '1'::double precision,    --df1  
                'NaN'::double precision    --df2 
            );
