When parsing a protocol, you will always encounter a variety of data conversion problems, from binary to Decimal, from byte string to integer, etc.Not much nonsense on that directly on the exampleBinary conversions between integers: 10-in-turn 16-in: Hex (==>) 0x10 16-in-turn 10-in: Int (' 0x10 ', +) ==> 16 Also similar to the OCT (), Bin ()----

The so-called ASCII and 16 binary are just conceptual things that are all binary in the computerThe conversion should be the output of the conversion, the same number, in the computer memory is the same, but the output is not the sameASCII is the encoding of characters, almost the encoding of characters on the keyboard.

For a complete description of Unicode, UTF-8, and UTF-16, see Wiki (UNICODE, UTF-8, UTF-16 ). In simple terms, Unicode defines all the numerical sets (called code point) that can be used to represent characters

Unicode encoding, Base: It assigns a unique integer to each character unit of all word systems in the world, which is between 0~1114111 and is called a code point in Unicode terms. and other character encodings are almost no different (for example, ASCII). The difference is that ASCII maps each index to a unique binary representation, but Unicode allows multiple code points with different binary encodings. Different encodings weigh between the number of strings required to store and the speed o

Coding knowledge Summary The earliest encoding is ASCII, which is only 1-127, expressed in one byte. And the first bit of this byte is 0.Later, many countries found that ASCII characters are too few. For example, Chinese characters cannot be expressed. Therefore, every country developed its own extended code, such as gb2312 in China, big5 of Taiwan, Japanese shift-JIS, etc. The extended code in each country is the same, that is, the extended code with the maximum length of 2 is used, wh

Today, when it comes to the question of string conversion to int, the conversion problem of signed number, we find that we need to look back into the problem of the system. Find some information, think can also, borrow a paragraph here and prepare to check.16 binary: Use 16 as the base counting system. 10 to 15 are represented by the number 0-9 and the letter a-f (or its uppercase a-f).Hexadecimal number co

Background Basics:1, character encoding related knowledge (transfer from http://blog.csdn.net/llwan/article/details/7567906)1.1, "character" is represented by a numberFirst to re-understand how the computer handles the "character", this principle is everyone must remember, especially in the Java writing program, it is absolutely not blurred. We know that computers use numbers to denote everything, and "character" is no exception. For example, we want to display an Arabic numeral "3", in our PC,

version of Unicode uses two bytes (16 bits) to represent all characters. . In fact, this is easy to produce ambiguity. We always think that two bytes represent two bytes stored in the computer. therefore, any character stored in Unicode occupies two bytes. in fact, this statement is incorrect. In fact, Unicode involves two steps. The first step is to define a specification and specify a unique number for all characters. This is completely a mathemati
