Changing fixed point representations is commonly called 'scaling'. If you can do this with a class with no performance penalty, then that's the way to go. It depends heavily on the compiler and how it inlines. If there is a performance penalty using classes, then you need a more traditional C-style approach.

WebFixed point iteration method. We can use the fixed-point iteration to find the root of a function. Given a function () which we have set to zero to find the root (() =), we rewrite the equation in terms of so that () = becomes = () (note, there are often many () functions for each () = function). Next, we relabel the each side of the equation ... WebFixed point acceleration algorithms Newton acceleration Here we will deﬁne g(x) = f(x) x. The general approach is to solve g(x) with a rootﬁnder. The x that provides this root will be a ﬁxed point. Thus after two iterates we can approximate the ﬁxed point with: Next guess = xi g(xi) g0(xi) (2) shutters bedroom windows
