The C++ <cmath> fmin() function returns minimum number between the two arguments. If one of the arguments is NaN, then the other argument is returned.

Syntax

double fmin (double x, double y);
float fmin (float x, float y);
long double fmin (long double x, long double y);
double fmin (Type1 x, Type2 y);                             

Parameters

x Specify value to compare.
y Specify value to compare.

Return Value

Returns the numerically minimum value.

Example:

In the below example, fmin() function is used to find out the minimum value between the two arguments.

#include <iostream>
#include <cmath>
using namespace std;
 
int main (){
  cout<<fmin(50, 100)<<"\n";
  cout<<fmin(5.5, 10.5)<<"\n";
  cout<<fmin(-2, 2)<<"\n"; 
  cout<<fmin(-3, -2)<<"\n";  
  return 0;
}

The output of the above code will be:

50
5.5
-2
-3
