fmax()

The fmax() function returns the larger of two arguments.

Syntax

fmax(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 fmax() function to find the larger value between 3 and 5:

#include <iostream>
#include <cmath>

int main() {
  double x = 3;
  double y = 5;
  double result;

  result = fmax(x, y);

  std::cout << "The larger value between " << x << " and " << y << " is " << result << "\n";
}

This produces the following output:

The larger value between 3 and 5 is 5

Codebyte Example
