Question

How to use fmax() function get larger of two floating point arguments in C++

Answer 1

#include <iostream>
#include <cmath>

using namespace std;

int main()
{
	cout << "fmax(10.0, 1.0) = " << fmax(10.0, 1.0) << endl;
	cout << "fmax(-10.0, 1.0) = " << fmax(-10.0, 1.0) << endl;
	cout << "fmax(-10.0, -1.0) = " << fmax(-10.0, -1.0) << endl;
	cout << "fmax(-INFINITY, 0) = " << fmax(-INFINITY, 0) << endl;
	cout << "fmax(NAN, -1) = " << fmax(NAN, -1) << endl;

	return 0;
}

/*
run:

fmax(10.0, 1.0) = 10
fmax(-10.0, 1.0) = 1
fmax(-10.0, -1.0) = -1
fmax(-INFINITY, 0) = 0
fmax(NAN, -1) = -1
