#include <math.h>
 
int main(int argc, char **argv)
{	
	printf("fmin(10.0, 1.0) = %.1f\n", fmin(10.0, 1.0));
	printf("fmin(-10.0, 1.0) = %.1f\n", fmin(-10.0, 1.0));
	printf("fmin(-10.0, -1.0) = %.1f\n", fmin(-10.0, -1.0));
	printf("fmin(-INFINITY, 0) = %.1f\n", fmin(-INFINITY, 0));
    printf("fmin(NAN, -1) = %.1f\n", fmin(NAN, -1));
	
    return 0;
}

/*
run:
  
fmin(10.0, 1.0) = 1.0
fmin(-10.0, 1.0) = -10.0
fmin(-10.0, -1.0) = -10.0
fmin(-INFINITY, 0) = -1.$ // -inf
fmin(NAN, -1) = -1.0
