C++ fmin() function

fmin() function is a library function of cmath header, it is used to find the minimum value of the given numbers, it accepts two number and returns the smaller one.

Syntax of fmin() function:

    fmin(x, y);

Parameter(s): x, y – are the numbers to be used to find the smaller value.

Return value: double – it returns double value that is the smaller value of x and y.

Example:

    Input:
    float x = 20;
    float y = 10;

    Function call:
    fmin(x,y);

    Output:
    10

C++ code to demonstrate the example of fmin() function

// C++ code to demonstrate the example of 
// fmin() function
#include <iostream>
#include <cmath>
using namespace std;

// main() section
int main()
{
    float x;
    float y;
    float result;
    
    //input the numbers
    cout<<"Enter first number : ";
    cin>>x;
    cout<<"Enter second number: ";
    cin>>y;
    
    //finding the minimum number
    result = fmin(x,y);
    cout<<"fmin("<<x<<","<<y<<"): "<<result;
    cout<<endl;
    
    return 0;
}

Output

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
