C++ fmin()

The fmin() function returns the smaller of two arguments.

Syntax

fmin(x, y)

The parameters x and y are usually a numeric data type ranging from negative to positive INFINITY. If one of the parameters is NaN, then the other parameter is returned.

Example

The following example uses the fmin() function to find the smaller value between 3 and 5:

#include <iostream>
#include <cmath>

int main() {
  double x = 3;
  double y = 5;
  double result;
  result = fmin(x, y);
  std::cout << "The smaller value between " << x << " and " << y << " is " << result << "\n";
}
