Help altering some code
f#

I need some help with the code below. At the moment the two players are having their priorMu and priorSigma values set in the code. I would like to have these values prompted for and input like the IsDraw and drawProb values. Can anyone help?

do

let noPlayers = 2
let isDraw =
printf "Draw (Y/N): "
(Console.ReadLine ()).ToUpper() = "Y"
let drawProb =
printf "Draw Probability (0 - 100): "
float (Console.ReadLine ())
let priorMu = 25.0<SkillPoints>
let priorSigma = priorMu / 3.0
let priorSkills = Array.init noPlayers (fun i -> Gaussian.Create (priorMu, priorSigma))
let draws = Array.create (noPlayers-1) isDraw
let (posteriorSkills, logZ) =
NPlayerTrueSkillUpdate (0.5*priorSigma, 0.01*priorSigma, 1e-4</SkillPoints> , drawProb / 100.0) (priorSkills,draws)

posteriorSkills |> Array.iteri (fun i postSkill ->
let priorSkill = priorSkills.[i]
printfn "Player %2d: %6.3f +/- %6.3f ==> %6.3f +/- %6.3f" i
(float priorSkill.Mean) (float priorSkill.StandardDeviation)
(float postSkill.Mean) (float postSkill.StandardDeviation)
)
printfn "\nProbability of match outcome = %6.3f" (exp (logZ) * 100.0)
Console.ReadLine () |> ignore

P.S. Why has that annoying lightbulb replaced the index value [ i ]

.

Something like:

1
2
3

let priorMu=
    print "priorMu: "
    float(Console.ReadLine()) * 1.0<SkillPoint>

The lightblub is just annoying feature of this forum, it's trying to show emoticons.

Thanks,
Rob

Thanks Robert.

let priorMuPlayer1=
print "priorMu Player 1: "
float(Console.ReadLine()) * 1.0<SkillPoint>
let priorMuPlayer2=
print "priorMu Player 2: "
float(Console.ReadLine()) * 1.0<SkillPoint>

would promt for the two values but how do I then initialise the array.

let priorSkills = Array.init noPlayers (fun i -> Gaussian.Create (priorMu, priorSigma))

P.S. How are you colouring your code syntax.
