CalculatePayoutForOutcome Consistency

[pwdel]

In calculating dbpm outcome, we should hypothetically use the dbpm outcome calculator and if the outcome is either YES or NO, we should resolve R to 1 or 0 rather than using the YES or NO patch method shown below.

This will make our calculations more consistent and re-use code.

// calculatePayoutForOutcome calculates the payout for a specific outcome.
// betInput is the outcome of the bet (e.g., "YES", "NO").
// marketResolutionInput is the outcome to calculate the payout against (e.g., market resolution).
// See README/README-MATH-PROB-AND-PAYOUT.md#market-outcome-update-formulae---divergence-based-payout-model-dbpm
func CalculatePayoutForOutcomeDBPM(bet models.Bet, totalYes, totalNo int64, betInput, marketResolutionInput string) float64 {
	if betInput != marketResolutionInput {
		return 0 // No payout if the bet's outcome doesn't match the market resolution
	}

	var totalPoolForOutcome int64
	if marketResolutionInput == "YES" {
		totalPoolForOutcome = totalYes
	} else {
		totalPoolForOutcome = totalNo
	}

	// prepare calculation by converting to float64
	totalPool := float64(totalYes) + float64(totalNo)

	// convert to float64 to do course payout calculation with float64 output
	return (float64(bet.Amount) / float64(totalPoolForOutcome)) * totalPool
}
