How to implement absolute value in C language: 1. If it is an integer number, you can use the abs function to get its absolute value; 2. If it is a floating-point number, you can use the fabs function to get its absolute value.
The operating environment of this article: Windows 7 system, Dev-C version 5.11, Dell G3 computer.
How to implement absolute value in C language:
1. In C language, you can use the abs or fabs function to get the absolute value of a number, which is contained in math.h header file, so add the header file to the code first, as shown in the figure below.
#2. If it is an integer number, you can use the abs function to get its absolute value. The code is as shown in the figure below.
#3. If it is a floating-point number, you can use the fabs function to get its absolute value. The code is as shown in the figure below.
#4. Finally, you can use the Printf function to print out the numbers converted into absolute values and view the code running results, as shown in the figure below.
#5. After debugging and running the code, you can see the result after converting the number into an absolute value, as shown in the figure below.
The above is the detailed content of How to calculate the absolute value in C language. For more information, please follow other related articles on the PHP Chinese website!
Mastering C# .NET Design Patterns: From Singleton to Dependency InjectionMay 09, 2025 am 12:15 AMDesign patterns in C#.NET include Singleton patterns and dependency injection. 1.Singleton mode ensures that there is only one instance of the class, which is suitable for scenarios where global access points are required, but attention should be paid to thread safety and abuse issues. 2. Dependency injection improves code flexibility and testability by injecting dependencies. It is often used for constructor injection, but it is necessary to avoid excessive use to increase complexity.
C# .NET in the Modern World: Applications and IndustriesMay 08, 2025 am 12:08 AMC#.NET is widely used in the modern world in the fields of game development, financial services, the Internet of Things and cloud computing. 1) In game development, use C# to program through the Unity engine. 2) In the field of financial services, C#.NET is used to develop high-performance trading systems and data analysis tools. 3) In terms of IoT and cloud computing, C#.NET provides support through Azure services to develop device control logic and data processing.

The Community of C# .NET Developers: Resources and SupportMay 06, 2025 am 12:11 AMThe C#.NET developer community provides rich resources and support, including: 1. Microsoft's official documents, 2. Community forums such as StackOverflow and Reddit, and 3. Open source projects on GitHub. These resources help developers improve their programming skills from basic learning to advanced applications.
The C# .NET Advantage: Features, Benefits, and Use CasesMay 05, 2025 am 12:01 AMThe advantages of C#.NET include: 1) Language features, such as asynchronous programming simplifies development; 2) Performance and reliability, improving efficiency through JIT compilation and garbage collection mechanisms; 3) Cross-platform support, .NETCore expands application scenarios; 4) A wide range of practical applications, with outstanding performance from the Web to desktop and game development.
Is C# Always Associated with .NET? Exploring AlternativesMay 04, 2025 am 12:06 AMC# is not always tied to .NET. 1) C# can run in the Mono runtime environment and is suitable for Linux and macOS. 2) In the Unity game engine, C# is used for scripting and does not rely on the .NET framework. 3) C# can also be used for embedded system development, such as .NETMicroFramework.
The .NET Ecosystem: C#'s Role and BeyondMay 03, 2025 am 12:04 AMC# plays a core role in the .NET ecosystem and is the preferred language for developers. 1) C# provides efficient and easy-to-use programming methods, combining the advantages of C, C and Java. 2) Execute through .NET runtime (CLR) to ensure efficient cross-platform operation. 3) C# supports basic to advanced usage, such as LINQ and asynchronous programming. 4) Optimization and best practices include using StringBuilder and asynchronous programming to improve performance and maintainability.
C# as a .NET Language: The Foundation of the EcosystemMay 02, 2025 am 12:01 AMC# is a programming language released by Microsoft in 2000, aiming to combine the power of C and the simplicity of Java. 1.C# is a type-safe, object-oriented programming language that supports encapsulation, inheritance and polymorphism. 2. The compilation process of C# converts the code into an intermediate language (IL), and then compiles it into machine code execution in the .NET runtime environment (CLR). 3. The basic usage of C# includes variable declarations, control flows and function definitions, while advanced usages cover asynchronous programming, LINQ and delegates, etc. 4. Common errors include type mismatch and null reference exceptions, which can be debugged through debugger, exception handling and logging. 5. Performance optimization suggestions include the use of LINQ, asynchronous programming, and improving code readability.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
