I have to involve experimental data in my code by addressing a method for automated generation of non-trivial input test data.How can I do this,considering the fact that I also have to take into consideration numbers of `double`

type?

Here's some additional context.From page 139 from this book http://mimoza.marmara.edu.tr/~msakalli/cse706_12/SkienaTheAlgorithmDesignManual.pdf which is more accurately page 151 from the PDF,I had to solve problem 4.3,which I did.However I need to generate random input for this problem,and since I have to deal with real numbers,it will most likely be needed to generate `double`

numbers.Problem is I don't know what range I should choose for this case when generating real numbers.

for examle 0 to max:

or from -max to max
