See the notes at the beginning of this chapter or section for information on using printf() or scanf() (and other functions reading and writing the stdin or stdout streams) in the example code.

#include <math.h>
#include <stdio.h>

int main(void)
{
  double x, y, z;

  x = -5.7;

  z = fmax(x, y);
  printf("The larger of %f and %f is %f\n\n", x, y, z);
}

Example Output

The larger of -5.700000 and 2.000000 is 2.000000
