hypot calculates the Euclidean distance between the origin (0,0) and a point represented by the Cartesian coordinates (x,y). hypotf differs only in the type of its arguments and result.### Returns
Normally, the distance value is returned. On overflow, hypot returns HUGE_VAL and sets errno to ERANGE. You can change the error treatment with matherr.
