本书深入讲解了有关Java的数值计算，并介绍了常见的Java数值方法及计算特性。全书分为4个部分，共16章，首先对Java的数据表示、数据类型及相关标准进行了详细的介绍。然后，作者分析了数值求根、数值求和、插值、估计、数值积分、求解微分方程等常见的数值计算；讨论了矩阵运算软件包，并讲解了各种矩阵运算的方法。最后，本书给出了一些有趣的数学计算实例。全书内容新颖，举例丰富，而且应用了大量生动的交互式图形程序。 本书适合于有兴趣学习Java数值方法的程序设计者，同时对于从事数值计算及相关工作的人员也具有很好的参考价值。-In Java Number Cruncher, author Ronald Mak explains how to spot-and how to avoid-the subtle programming miscues that can cause vexing calculation errors in your applications. An authority on mapping pure math to computer math, he explains how to use the often-overlooked computational features of Java, and does so in a clear, non-theoretical style. Without getting lost in mathematical detail, you ll learn practical numerical algorithms for safely summing numbers, finding roots of equations, interpolation and approximation, numerical integration, solving differential equations, matrix operations, and solving sets of simultaneous equations. You ll also enjoy intriguing topics such as searching for patterns in prime numbers, ge

PB中的套接字是通过Winsock.pbl库来提供的，它封装了套接字编程中用到的数据结构和过程，在功能上类似于VB中的Winsock控件-PB through the socket to provide Winsock.pbl library, and it encapsulates socket programming used in the data structure and process functions similar to VB

ConvertVB6toVB7: This application does the form painting depending upon the VB6 from file. It uses a XML file to get most of the changed Valued from VB6 to VB7 It relies mostly on the XMl file VB7.xml we can make this program more generic as it s depends upon XML file for data transfer. The logic are mostly there and can be extended to perform most of the task Some task are left. The problem with VB7 is with Control Array It is not handeld in the Program. For this to run u require Viusal Studio.NET Hapy new Year and best of luck.-ConvertVB6toVB7: This application does the form painting depending upon the VB6 from file.
