signed vs unsigned binary

The first clear 4 byte int can represent the range of numbers is 2147483647 ——-2147483648, to see the problem I encountered:The "equality" description is output here.(INT_MIN==-2147483648)Is true.Output "1(1Is true, but this is unscientific.Output "

Today, online brush questions, one of the problems always results and expectations are not the same, in time and again check the program logic, confirm the correct, or can not pass, forced to use vs Start debugging!Here is my program code:1

1. Signed number and unsigned numberThe signed number is the highest bit ,0 for Positive, and1 for negative .The highest bit of unsigned number is not a sign bit , but a part of a number.1011 1111 0000 1111 1111 0000 1011 1010 If there is a

First, the CONVERT functionCharacter Set conversions: convert (XXX USING gb2312) type conversions are the same as SQL Server, but differ on type parameters: CAST (xxx as type), convert (XXX, type), type must be of the following type:Available type

One, Java bit operation1. Presentation method:In the Java language, the binary number is represented by a complement, the highest bit is the sign bit, the sign bit for positive numbers is 0, and the negative is 1. The complement representation needs

in the computer, use BITS to store information. The same bit-level representation, changing the way it is interpreted, expresses different information. 0. XOR in bit-level operationsA bit-level operation should be noted that the difference or this

Meaning of 0 and 1:In the computer 0 and the switch representing the logic circuit, where 1 is closed and 0 is disconnected.0 and 1 can be used to represent all the data in the computer, such as colors, pictures, videos, executable programs, such as

Use vstruct to parse binary data Vstruct is a module written purely in Python and can be used for parsing and serializing binary data. In fact, Vstruct is a submodule of the vivisect project, which is initiated by Invisig0th Kenshoto and is

PHP/*There are 4 bit operations in the *php, respectively, & and | or ^ XOR ~ Take counter & two bits are all 1, the result is that 1| has one for 1, the result is 1^ one is 0, one is 1, the result is 1~ take anti-0->1,1->01. The highest bit of the
