Question

So I have a function SolveEquasion that returns a pair float*float[]. What is the best way to print the number and the array and continue working with the array? I made the following code but it seems there is a better way

...
|> SolveEquasion
|> (fun (det, solution) -> printfn "Determinant = %f\nSolution = %A" det (Array.toList solution), solution )
|> snd

Answer 1

Well, for one thing you can skip the use of snd by returning a single value rather than a tuple from the previous function:

...
|> SolveEquasion
|> (fun (det, solution) -> 
        printfn "Determinant = %f\nSolution = %A" det (Array.toList solution) 
        solution )
