      F_TYPE hypot (F_TYPE x, F_TYPE y)

1  –  Description

    hypot() computes the length of the hypotenuse of a right
    triangle, where x and y represent the perpendicular sides of
    the triangle.

    hypot(x,y) is defined as the square root of (x**2 + y**2) and
    returns the same value as cabs(x,y).
