|Description||The hypot() function returns sqrt(x*x + y*y). This is the length of the hypotenuse of a right triangle with sides of length x and y, or the distance of the point (x, y) from the origin. Using this function instead of the direct formula is wise, since the error is much smaller. No underflow with small x and y. No overflow if result is in range.|
