The algorithm (1.2) is an example of what is known as fixed-point iteration, in which one hopes to find a fixed point, that is, an x where the iteration quits changing. A fixed point is thus a point x where x = 1 2 (x+ y/x). (1.3) More precisely, x is a fixed point of the function f(x)=1 2 (x +y/x), (1.4) defined, say, for x $= 0.
