This highly comprehensive handbook provides a substantial advance in the computation of elementary and special functions of mathematics, extending the function coverage of major programming languages well beyond their international standards, including full support for decimal floating-point arithmetic. Written with clarity and focusing on the C language, the work pays extensive attention to little-understood aspects of floating-point and integer arithmetic, and to software portability, as well as to important historical architectures. It extends support to a future 256-bit, floating-point format offering 70 decimal digits of precision. Select Topics and Features: references an exceptionally...
Shell scripting skills never go out of style. It's the shell that unlocks the real potential of Unix. Shell scripting is essential for Unix users and system administrators-a way to quickly harness and customize the full power of any Unix system. With shell scripts, you can combine the fundamental Unix text and file processing commands to crunch data and automate repetitive tasks. But beneath this simple promise lies a treacherous ocean of variations in Unix commands and standards. Classic Shell Scripting is written to help you reliably navigate these tricky waters.Writing shell scripts requires more than just a knowledge of the shell language, it also requires familiarity with the individual...
The PHP scripting language and MySQL open source database are quite effective independently, but together they make a simply unbeatable team. When working hand-in-hand, they serve as the standard for the rapid development of dynamic, database-driven websites. This combination is so popular, in fact, that it's attracting manyprogramming newbies who come from a web or graphic design background and whose first language is HTML. If you fall into this ever-expanding category, then this book is for you. Learning PHP and MySQL starts with the very basics of the PHP language, including strings and arrays, pattern matching and a detailed discussion of the variances in different PHP versions. Next, it...
Text on momentum, energy, and mass transfer for graduate engineering students.
You may have seen Unix quick-reference guides, but you've never seen anything likeUNIX in a Nutshell. Not a scaled-down quick reference of common commands,UNIX in a Nutshellis a complete reference containing all commands and options, along with generous descriptions and examples that put the commands in context. For all but the thorniest Unix problems, this one reference should be all the documentation you need. The third edition ofUNIX in a Nutshellincludes thorough coverage of System V Release 4. To that, author Arnold Robbins has added the latest information about: Sixty new commands inThe Alphabetical Summary of Commands Solaris 7 Shell syntax (sh,csh, and the 1988 and 1993 versions ofks...
This contributed volume honors the 80th birthday of Frank Stenger who established new Sinc methods in numerical analysis.The contributions, written independently from each other, show the new developments in numerical analysis in connection with Sinc methods and approximations of solutions for differential equations, boundary value problems, integral equations, integrals, linear transforms, eigenvalue problems, polynomial approximations, computations on polyhedra, and many applications. The approximation methods are exponentially converging compared with standard methods and save resources in computation. They are applicable in many fields of science including mathematics, physics, and engineering.The ideas discussed serve as a starting point in many different directions in numerical analysis research and applications which will lead to new and unprecedented results. This book will appeal to a wide readership, from students to specialized experts.
For system administrators, programmers, and end users, shell command or carefully crafted shell script can save you time and effort, or facilitate consistency and repeatability for a variety of common tasks. This cookbook provides more than 300 practical recipes for using bash, the popular Unix shell that enables you to harness and customize the power of any Unix or Linux system. Ideal for new and experienced users alike—including proficient Windows users and sysadmins—this updated second edition helps you solve a wide range of problems. You’ll learn ways to handle input/output, file manipulation, program execution, administrative tasks, and many other challenges. Each recipe includes one or more scripting examples and a discussion of why the solution works. You’ll find recipes for problems including: Standard output and input, and executing commands Shell variables, shell logic, and arithmetic Intermediate shell tools and advanced scripting Searching for files with find, locate, and slocate Working with dates and times Creating shell scripts for various end-user tasks Working with tasks that require parsing Writing secure shell scripts Configuring and customizing bash

This practical guide serves as both a reference and tutorial for POSIX-standard awk and for the GNU implementation, called gawk . This book is useful for novices and awk experts alike. In this thoroughly revised edition, author and gawk lead developer Arnold Robbins describes the awk language and gawk program in detail, shows you how to use awk and gawk for problem solving, and then dives into specific features of gawk .
Although the World Wide Web is enjoying enormous growth rates, many Web publishers have discovered that HTML is not up to the requirements of modern corporate communication. For them, Adobe Acrobat offers a wealth of design possibilities. The close integration of Acrobat in the World Wide Web unites the structural advantages of HTML with the comprehensive layout possibilities of Portable Document Format (PDF). On the basis of practical examples and numerous tricks, this book describes how to produce PDF documents efficiently. Numerous tips on integrating Acrobat into CGI, JavaScript, VBScript, Active Server Pages, search engines, and so on make the book a mine of information for all designers and administrators of Web sites.
