C ++中的restder()
在这里，我们将看到remainder()C++方法的功能。该remainder()函数用于计算分子/分母的浮点余数。
因此，余数(x,y)将如下所示。
remainder(x, y) = x – rquote * y
rquote是x/y的值。这四舍五入为最接近的整数值。此函数接受double，float，longdouble类型的两个参数，并返回相同类型的剩余部分，该部分作为参数给出。第一个参数是分子，第二个参数是分母。
示例
#include <iostream>
#include <cmath>
using namespace std;
main() {
double x = 14.5, y = 4.1;
double res = remainder(x, y);
cout << "Remainder of " << x << "/" << y << " is: " << res << endl;
x = -34.50;
y = 4.0;
res = remainder(x, y);
cout << "Remainder of " << x << "/" << y << " is: " << res << endl;
x = 65.23;
y = 0;
res = remainder(x, y);
cout << "Remainder of " << x << "/" << y << " is: " << res << endl;
}输出结果
Remainder of 14.5/4.1 is: -1.9 Remainder of -34.5/4 is: 1.5 Remainder of 65.23/0 is: nan
