    var x int

    var y float64

ИЛИ:

package main
import (
    "fmt"
    "math"
)

func main() {
    var x, y, z, workers float64
    fmt.Scanln(&x)
    fmt.Scanln(&y)
    fmt.Scanln(&z)
    fmt.Scanln(&workers)

    var wine = 0.4 * x * y / 2.5;

    if (wine < z) {
        fmt.Printf("It will be a tough winter! More %d liters wine needed.", int(z - wine))
    } else {
        fmt.Printf("Good harvest this year! Total wine: %d liters.\n%d liters left -> %d liters per person.",
                    int(wine), int(math.Ceil(wine - z)), int(math.Ceil((wine - z) / workers)))
    }
}
