hypot, hypotf, hypotl - Euclidean distance function

 I double hypot(double  x , double  y );

I long double hypotl(long double  x , long double  y );

The R hypot () function returns sqrt(x*x+y*y). This is the length of the hypotenuse of a right-angle triangle with sides of length x and R y , or the distance of the point (x,y) from the origin.
