所以你可以看到我的问题了吗？你可以将数字归零：
BigInteger number = new BigInteger("2");
BigInteger sum;
BigDecimal weight;
BigDecimal finalweight;
for(int i = 1; i <= 64; i++){
sum = number.pow(i).subtract(new BigInteger("1"));
weight = new BigDecimal(sum.multiply(new BigInteger("25")),9);
System.out.print("Sum after spot " + i + ": " + sum);
System.out.println(" weight in kg: " + weight);
try{Thread.sleep(500);}
catch(Exception e){System.out.println("Error");};
}
