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 ... Web6. 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.
