Syntax

#include <math.h>
double hypot(double side1, double side2);

hypot calculates the length of the hypotenuse of a right-angled triangle based on the lengths of two sides side1 and side2. A call to hypot is equivalent to:

   sqrt(side1 * side1 + side2 * side2);

hypot returns the length of the hypotenuse. If an overflow results, hypot sets errno to ERANGE and returns the value HUGE_VAL. If an underflow results, hypot sets errno to ERANGE and returns zero.

This example calculates the hypotenuse of a right-angled triangle with sides of 3.0 and 4.0.

#include <math.h>

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

   x = 3.0;
   y = 4.0;
   z = hypot(x, y);
   printf("The hypotenuse of the triangle with sides %lf and %lf"
   " is %lf\n", x, y, z);
   return 0;

   /****************************************************************************
      The output should be:

     The hypotenuse of the triangle with sides 3.000000 and 4.000000 is 5.000000
