What is the unsigned binary integer 01001001 converted into a decimal integer?
The unsigned binary integer 01001001 converted into a decimal integer is 73.
The rule of converting binary to decimal is to expand the binary number in bit-weighted form into a polynomial sum and find the final sum.
Introduction to computer number system:
Number system: counting method, which refers to a method of expressing numerical values using a set of fixed symbols and unified rules
Number: exponent The position of a character symbol in a number
Base number: refers to the number of digital symbols that can be used in a certain carry counting system
Bit weight: refers to the number of digit symbols that can be used in a certain carry counting system In this carry counting system, the size represented by the digit is the size of the value represented by "1" in a certain digit.

How to calculate binary arithmetic
Jan 19, 2024 pm 04:38 PM
Binary arithmetic is an operation method based on binary numbers. Its basic operations include addition, subtraction, multiplication and division. In addition to basic operations, binary arithmetic also includes logical operations, displacement operations and other operations. Logical operations include AND, OR, NOT and other operations, and displacement operations include left shift and right shift operations. These operations have corresponding rules and operand requirements.
What are the two major improvements of EDVAC?
Mar 02, 2023 pm 02:58 PM
EDVAC has two major improvements: one is the use of binary, and the other is the completion of stored programs, which can automatically advance from one program instruction to the next, and its operations can be automatically completed through instructions. "Instructions" include data and programs, which are input into the memory device of the machine in the form of codes, that is, the same memory device that stores data is used to store instructions for performing operations. This is the new concept of so-called stored programs.
How to convert binary to hexadecimal using C language?
Sep 01, 2023 pm 06:57 PM
Binary numbers are represented by 1s and 0s. The 16-bit hexadecimal number system is {0,1,2,3…..9,A(10),B(11),…F(15)} in order to convert from binary representation to hexadecimal Represents that the bit string ID is grouped into 4-bit chunks, called nibbles starting from the least significant side. Each block is replaced with the corresponding hexadecimal number. Let us see an example to get a clear understanding of hexadecimal and binary number representation. 001111100101101100011101 3 E 5 B&nb
How to read binary files in Golang?
Mar 21, 2024 am 08:27 AM
How to read binary files in Golang? Binary files are files stored in binary form that contain data that a computer can recognize and process. In Golang, we can use some methods to read binary files and parse them into the data format we want. The following will introduce how to read binary files in Golang and give specific code examples. First, we need to open a binary file using the Open function from the os package, which will return a file object. Then we can make
What is the main reason for using binary within computers?
Apr 04, 2019 pm 02:25 PM
The main reasons why computers use binary systems: 1. Computers are composed of logic circuits. Logic circuits usually only have two states, the switch is on and off, and these two states can be represented by "1" and "0"; 2. Only two numbers, 0 and 1, are used in the binary system, which is less error-prone during transmission and processing, thus ensuring high reliability of the computer.

Mar 15, 2024 pm 04:45 PM
Title: Easily learn to convert hexadecimal to binary in Go language. Specific code examples are required. In computer programming, conversion operations between different base numbers are often involved. Among them, conversion between hexadecimal and binary is relatively common. In the Go language, we can achieve hexadecimal to binary conversion through some simple code examples. Let us learn together. First, let's take a look at the representation methods of hexadecimal and binary. Hexadecimal is a method of representing numbers, using 0-9 and A-F to represent 1
How to express negative numbers in binary
Nov 23, 2023 pm 04:11 PM
Negative numbers are represented in computers using two's complement, that is, negative numbers are represented by the two's complement of positive numbers.
Can Golang handle binary files?
Mar 20, 2024 pm 04:36 PM
Can Golang handle binary files? In Go language, processing binary files is very common and convenient. By using built-in packages and methods we can easily read, write and manipulate binary files. This article explains how to handle binary files in Go and provides specific code examples. Reading Binary Files To read a binary file, we first need to open the file and create a corresponding file object. We can then use the Read method to read the data from the file and store it in bytes in
