fmin()函数fmin()函数是cmath标头的库函数,用于查找给定数字的最小值,它接受两个数字并返回较小的一个。
fmin()函数语法:
fmin(x, y);
参数: x,y –是用于查找较小值的数字。
返回值: double-它返回double值,它是x和y中的较小值。
示例
Input: float x = 20; float y = 10; Function call: fmin(x,y); Output: 10
fmin()函数示例//示例
// fmin()功能
#include <iostream>
#include <cmath>
using namespace std;
// main()部分
int main(){
float x;
float y;
float result;
//输入数字
cout<<"Enter first number : ";
cin>>x;
cout<<"Enter second number: ";
cin>>y;
//找到最小数量
result = fmin(x,y);
cout<<"fmin("<<x<<","<<y<<"): "<<result;
cout<<endl;
return 0;
}输出结果
First run: Enter first number : 10 Enter second number: -20 fmin(10,-20): -20 Second run: Enter first number : 10 Enter second number: 20 fmin(10,20): 10 Third run: Enter first number : 123.90 Enter second number: 121.88 fmin(123.9,121.88): 121.88 Fourth run: Enter first number : -123.45 Enter second number: -121.56 fmin(-123.45,-121.56): -123.45
