Java剩余整数除法? [英] Java Remainder of Integer Divison?

问题描述

我一直在搜索有关此主题的信息，但我仍然听不懂，如果有人可以详细说明，我将非常感激.

I was searching around about this topic but I still don't get it, if someone can elaborate I would be very thankful.

我的任务是将两个变量除以整数除法. 问题是，我不知道余数是什么，现在我做了类似的事情，这是我通过互联网搜索发现的:

My task is to divide two variables as integer division with remainder.. The problem is, that I have no clue what a remainder is, for now I did something like that, this is what I found by searching through the internet:

int a;
int b;
int remainder = Math.Pow(a,2) % b;

System.out.println("a^2 / b = " + Math.Pow(a,2) / b);
System.out.println("remainder = " + remainder);

例如，如果我设置了(a = 43)和(b = 67)

if I for example set (a = 43) and (b = 67)

然后我会得到这个结果:

Then I will get this reslut:

a^2 / b = 27
remainder = 40

现在，由于我不知道剩下的是什么(这只是互联网的建议)，我不知道这是否是正确的答案.?

Now since I have no idea what the remainder is (this is just a suggestion form the internet) I have no idea if this is the correct answer..?

感谢您的帮助，

亲切的问候

推荐答案

如果您正在寻找数学模运算，可以使用

If you are looking for the mathematical modulo operation you could use

int x = -22;
int y = 24;
System.out.println(Math.floorMod(x, y));

如果您对数学模数不感兴趣(仅余数)，则可以使用

If you are not interested in the mathematical modulo (just the remainder) then you could use

int x = -22;
int y = 24;
System.out.println(x%y);
