说明：  许多现代浮点单元的一项主要体系结构功能，是能够将一个乘法与后面紧跟的加法作为单个运算执 行，且没有中间舍入误差。例如，Intel 的 Itanium 体系结构提供了一些指令，将三元运算 (a*b+c) 、(a*b-c) 和 (c-a*b) 中的每一个都组合为单个浮点指令（分别为 fma、fms 和 fnma）。这些单个 指令都比执行独立的乘法和加法指令快，并且因为没有中间乘法舍入，所以更为精确。该优化可以显 著提高那些含有多个交错乘法和加法运算的函数的速度(many modern floating point unit of a major system structure and function is to be a follow closely behind multiplication and addition of implementation as a single operator, with no intermediate rounding error. For example, Intel's Itanium architecture provides a number of directives to the ternary operator (a* b, c), (a* b-c) and (c-a* b) each have a portfolio to a single floating point instructions (Fullmetal respectively, and fms fnma) . These individual instruction than the implementation of an independent and additive multiplication instructions quickly, and because no middle multiplication into homes, so more precise. The optimization can significantly increase those containing more than staggered multiplication and addition operations function of the speed)

很好的BMP转JPG，有VB原代码及操作界面(good JPG, VB source code and user interface)

再发一个文字滚动，基于VB代码,很不错的VB源码，适合VB爱好者学习研究。(And then send a text to scroll through the VB code, it is a good VB source code for VB lovers learn.)

VC++ 界面优化的例程，界面优化皮肤，例程是一个猜数字的对话框(VC++ Interface optimized routines, interface optimization of the skin, routine is a dialog box猜数字)

说明：  一个关于window界面的程序代碼：實習了可改變可停靠工具栏大小的功能。(a window on the interface code : attachment of the change will be docked toolbar size functions.)

As the name implies, the form is transparent(As the name the implies that the form is transparent)

mfc界面实例，其中含有多个实例，由浅入深(mfc interface instance, which contains more than one instance, Deep)

一个界面例子，设计得还不错，和大家一起分享，共同进步(Example of an interface, designed to be pretty good, and the U.S. share common progress)

说明：  计算器的VC程序，界面友好，易于操作，资源不错(Calculator VC program, user-friendly, easy to operate)
