fmin()函数以及C ++中的示例
C++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
C++代码演示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
