Linus Torvalds may be best known as the creator of Linux, but some argue that his creation of Git has had a greater impact on the world. Again, although

We often say: know what is, but also know why. Learning a method and solving a problem in practice can only mean mastering the What and How of the method. Therefore, we need to talk about object-oriented analysis and design methods from a relatively primitive point of view, namely the basic fact of complexity.

Some argue that a "type system" is an effective syntax for classifying statements according to worthy types to find program defects or bad behavior. There are a few points worth debating about this definition. First of all, this definition says that type systems are for "programming," but they have broader applications in mathematics, logic, and philosophy. However, this book focuses on type systems in programming. Its...

Recently, a friend said that he wanted to say that he was learning Java recently, and he still did not understand object-oriented programming language, in order to help him faster "transition", I wrote this article. Because at the superstructure level. All object-oriented programming languages have the same idea, and these three features are the backbone of the idea, and I will focus on the Java three features. Object-oriented...

What does that tell us? That means the computer can't tell the difference between the two numbers. Why is that? So to understand what's really going on, we should take a look at these two decimal floating point numbers in binary space. Well, obviously, they do have different binary representations, as it should. This is about to talk about the accuracy of floating points. So for the above value 0.99999...
