A few curried closures, groovy style

curried-closure.groovy

    def calculatePrice = { float cost, float margin, float vat ->
        (cost + margin) * (100 + vat)/100
    }

    def standardRatePrice = calculatePrice.rcurry(20.0f)
    def reducedRatePrice = calculatePrice.rcurry(5.0f)
    def zeroRatePrice = calculatePrice.rcurry(0.0f)

    void run() {
        println standardRatePrice(10.0, 2.5)
        println reducedRatePrice(10.0, 2.5)
        println zeroRatePrice(10.0, 2.5)
    }
