Java 小数点位置的问题。我有一个forumla，需要平均值在小数点后的右边

所以我想我基本上得到了你想要得到的。我不能让平均数前面没有零，但击球平均数和击球百分比都有3位小数。基本上我修正的是将At-bats（bats）变成一个双倍值而不是一个整数，并将模函数变成除法。下面是代码的样子

  batavg = (single + Double + triple + hr) % bats;
  slug = ((single) + (Double*2) + (triple*3) + (hr*4)) % bats;
  
  System.out.println("Player name: " + player);
  System.out.printf("The currnet players batting average is: %.3f\n",  batavg);
  System.out.printf("The current players Slugging Average is : %.3f\n", slug);

如果你有任何问题，请告诉我。祝你好运。

你确定要使用

%

？你说“平均值必须在小数点后的右边”是什么意思？你能给出一个输入和输出的示例吗？那么你希望340.000是340.000？340.5或340.9怎么样？340是我想要的样子。所以把你的数字除以1000？

//code for each int of hits are not shown

double bats = 35.0;   //this is used as a baseline
String player = "PLAYER";
double batavg;
double slug;
batavg = (single + Double + triple + hr) / bats;  //division sign used instead of % 
//(modulus will not work for this)
slug = ((single) + (Double*2) + (triple*3) + (hr*4)) / bats;

System.out.println("Player name: " + player);

System.out.printf("The current players batting average is: %.3f\n",  batavg);  
  //now there will be a decimal and 3 numbers after
System.out.printf("The current players Slugging Percentage is : %.3f\n", slug);
