import java.util.Scanner;
public class JavaApplication3 {
    public static void main(String[] args){

double baseDiamond, baseDiamondPrice, preDiamond, preDiamondPrice, baseDiamondCalc, finalECoins;
Scanner input = new Scanner(System.in);


System.out.print("What is your current Diamond Miner level? ");
preDiamondPrice = input.nextDouble();
System.out.print("Enter what diamondminer level ");
baseDiamondPrice = input.nextDouble();
while (baseDiamondPrice > 0) {
    baseDiamondPrice = ((baseDiamondPrice * 500000) + 1000000);
    baseDiamondPrice--;
}
while (preDiamondPrice > 0) {
    preDiamondPrice = ((preDiamondPrice * 500000) + 1000000);
    preDiamondPrice--;
}
baseDiamondCalc = (baseDiamondPrice - preDiamondPrice);


DecimalFormat dRemover = new DecimalFormat("0.#");
System.out.println("You need " +dRemover.format(baseDiamondCalc)+ " ecoins for diamond miner level "+dRemover.format(baseDiamondPrice)+".");
    }}
