i wanted calculate multiplicative inverse of positive real number without using division. after reading through various pages on newton raphson method, implemented following code calculating inverse: #define precision 0.1e-5 double inverse(double num) { double ans = num; while (ans * num > 1 + precision || ans * num < 1 - precision) { ans = ans * (2 - num * ans); } return ans; } now, problem is, not inverse value. loop goes on infinitely. so, 1st thing noticed was: value of ans become negative, added statement if (ans < 0) ans *= -1; so ans remains positive always. 2nd point noticed: if initialization ans = 0.5 correct answer few values of num = (1, 2, 3, 5) . so, assumption is, implementation isn't working because of inappropriate initialization of variable ans . so, questions: 1 .can method used calculate inverse of positive real numbers? 2 .if yes, there conditions required initial value assumed when using newton raphson m

as far know, swift allows set property observers either stored , computed properties. if computed property value depends on backing store, property observers not fired when these backing store values changed: public class baseclass { private var privatevar1: int = 0 private var privatevar2: int = 0 public var property: int { { return privatevar1 * privatevar2 } set { print("some setter without effect") } } private func changesomevalues() { privatevar1 = 1 privatevar2 = 2 } } public class subclass : baseclass { override var property: int { didset { print("didset \(property)") } } } didset of subclass isn't called when changesomevalues called. let's consider case: have such baseclass in third-party framework. define subclass in our app. question is: how can rely on subclass observers without knowledge property nature:
