问题描述
问题:
非常简单，但无法在程序中工作，需要帮助，我的大脑已经过度使用.
我正在尝试计算值并获取百分比，但最终却得到了0.
整数= 122333; (这里的值可能会扩展到十万)
整数b = 128222;值可以扩展到十万)
int answ = 0;
answ =(a-b);
answ = -5889;
answ =((answ/a)* 100);
answ = 0 =绝对错误
正确的答案应该是:(-4.81)
请增强我的基本代码以获得正确的值，因为我总是得到0

Questions:
Very easy but can''t work in program, need help my brain is over used.
I am trying to calculate the value and get the percentage but I end up getting a 0.
int a = 122333; (value here could expand to hundred thousand)
int b = 128222; value here could expand to hundred thousand)
int answ = 0;
answ = (a - b);
answ = -5889;
answ = ((answ / a) * 100);
answ = 0 = definitely wrong
CORRECT ANSWER SHOULD BE: (-4.81)
Please enhance my basic code to get the right value because I always get 0

推荐答案
answ = ((answ / a) * 100);
整数(-5889/122333)为 0 ， 0 * 100 为 0 ，因此您的程序是正确的.
整数(100 * answ/a)的计算结果为 -588900/122333 ，更接近您的愿望 -4 .
欢呼声，

The integer (-5889 / 122333) is 0, 0 * 100 is 0 so your program is correct.
The integer (100 * answ / a) would evaluate to -588900 / 122333 which is -4 nearer to your wish.
cheers,
AR
int answ = 0;
进入
Into
double answ = 0;
然后
then
answ = ((answ / a) * 100);//= -4,81390957468549
