How to simplify this JavaScript into something useable?

[Lukeidiot]

I am trying to make this complicated JavaScript into a more simple, workable approach.

 

Here is a link to the full source code:

I am trying to accomplish the following stats:

 

End Goal: Calculate Profit for Roll High and Roll Low

 

Here is the function I believe is responsible for calculating:

 

   namespace("Rollin.Casino.Dice.Stats", function() {

        var t, e;

        return t = namespace.use("Rollin.Casino.Dice.Dice"), e = function() {

            function e(t, e) {

                this.number = t, this.dice = e

            }

            return e.prototype.decimal = 5, e.prototype.getData = function(e, n, r) {

                var i, o, s, a, u;

                switch (r > t.MAX_NUMBER - 1 && (r = t.MAX_NUMBER - 1), r < t.MIN_NUMBER + 1 && (r = t.MIN_NUMBER + 1), i = this.dice.getFee(), n) {

                    case t.PREDICTION_BIGGER:

                        o = (100 - i) / (t.MAX_NUMBER - r), s = t.MAX_NUMBER - r;

                        break;

                    default:

                        o = (100 - i) / r, s = r

                }

                return a = e * o, u = a - e, a > 99999 && (a = 99999), u > 99999 && (u = 99999), a = this.number.floorDecimal(a, this.decimal), u = this.number.floorDecimal(u, this.decimal), this.number.isNaN(a) && (a = 0), this.number.isNaN(u) && (u = 0), {

                    multiplier: o,

                    odds: s,

                    payout: a,

                    profit: u

                }

            }, e

        }()

    }),

 

Here is the same function being used:

 

   t.prototype.changeStats_ = function() {

                var t, n, r, i;

                return t = this.dice.betAmount, i = this.dice.betNumber, n = this.stats.getData(t, e.PREDICTION_BIGGER, i), r = this.stats.getData(t, e.PREDICTION_SMALLER, i), this.element.find(".stats.high .profit").text(n.profit), this.element.find(".stats.high .odds").text(n.odds + "%"), this.element.find(".stats.low .profit").text(r.profit), this.element.find(".stats.low .odds").text(r.odds + "%")

            }

 

So, how can I make a simple function where I can calculate the profit by using something

 

such as this: calculateRollHighProfile(betsize, predictionNumber, houseEdge);

Please note: Profits are affected by house edges below:

Remember this?

expected profit = bet * odds of losing / odds of winning

Let's revise that a little bit to be more clear what it means. (It was late night when I wrote that and it made sense to me.)

expected profit = bet * (odds of not winning - house edge) / odds of winning

If you predict 88 then your high roll must be within 89-99 to win. That's 99 - 88 = 11 out of 100 (or 100% - 88% - 1% = 11%). Not winning would thus be 89%. If you wager 5 and the house gets 0.96% then

expected profit = 5 * (89 - 0.96) / 11 = 40.01818

Look familiar? I imagine that logic is buried somewhere in the Javascript, though it looks like they're using an alternative form that calculates gross and not net winnings. Same difference. Edited May 25, 2016 by requinix

Here is what I managed to come up with:

 

    function calculateRollLowProfit(game_int, bet, house_edge){


        var roll = game_int - 1;
        var game_int = 100 - game_int;
        var chance = (100 - game_int);
        var multiplier = (house_edge / chance);


        payout = bet * multiplier - bet;
        payout = toFixed(payout, 5);
        payout = parseFloat(payout);


        $('.low .profit2').text(payout);


    }
    function calculateRollHighProfit(game_int, bet, house_edge){


        var roll = game_int - 1;
        var chance = (99 - game_int);
        var multiplier = (house_edge / chance);


        payout = bet * multiplier - bet;
        payout = toFixed(payout, 5);
        payout = parseFloat(payout);


        $('.high .profit2').text(payout);


    }
