, exponent is the digit (single-precision 8-bit, double-precision 11-bit), fraction is a valid bit (single-precision 23-bit, double-precision 52-bit).This is not quite like the scientific notation that we usually use.But this approach poses a problem, that is, when the effective bit exceeds a certain time, there will be a precision problem.// true // falseYes, it's equal.Because the first two will be stored as 1.000 ... (52 x 0) x2539007199254740994 will be saved as 1.000 ... 0001x253.The effect

Zhihu answered a question about book recommendation: Which of the following are the best recommendations? If you only recommend a computer-type God book, it must be code: Language hiding behind computer software and hardware. Eager to communicate is the nature of most people. In this book, "encoding" usually refers to a system that converts information between humans and machines. In other words, encoding

Software environment: Generally including database (MYSQL,SQLSERVER,ORACLE,DB2), running middleware, namely application server, such as Tomcat,jetty,jboss,weblogic,webphere, and operating system environment, such as Windows,unix (Aix,solaris), each version of Linux and so on. Hardware environment: such as PC SERVER,IBM, HP, SUN (has been acquired by Oracle) smal

may be important. The collapse of the video compression chip is caused by the lattice shirt. Associate events. "It emits noise. Starting from 21:03:53, it lasted 4 seconds, which is much better than simply saying "it emits noise. Audit tracking for design is also very useful in testing. The software configuration control tool can tell you which revision introduced bugs. Record things! No matter how terrible the moment is, remember it in the

configuration options. Some of the options are determined by the motherboard design. Some options can be modified to improve the system performance. The main instructions are as follows: (1) CPU internal cache: Enable by default, which allows the system to use the first level of cache inside the CPU. 486 and 586-level CPUs generally carry cache, unless the system is abnormal when this item is set to enable, this item should not be easily changed. If this option is set to disabl E (disabled), t

the protagonist consciousness is still quite necessary, The initiative proposed to the company's existing external chain personnel and editorial staff to adjust, put forward the feasibility plan, to help improve the efficiency of other personnel, and thus promote the overall progress of the staff, such words are no harm, because at least the experience of ploy star, enterprising employees are favored more. G really know what you want before the interview. This is going to mention the SEO envir

Freebsd uses the overall solution and simple kernel to impress us. A bigger reason to use it is its outstanding software package management. The Free Software in unix/linux is much more convenient than that in windows, regardless of port or pkg_add. Back to the topic, everything can only be measured. Server hardware performance,

experience the advantages of drawing web, computer Hardware This part of the knowledge of three pages (soft book). But a lot of content. For those who develop software, it is also very necessary to understand the hardware. Summary by drawing. Computer hardware is composed of three parts CPU, memory, input and output.

. In addition, you need to configure the distribute mode and bit rate for each file during multi-file batch processing, and it is not convenient to modify the output file name. So in order to save time, I decided to write a tool to help me complete it. 2. So why should I use Windows Media Encoder to convert mp3 to WMA? Because my machine has a lot of MP3 files, I need to compress them. Since Microsoft has such a free tool, of course I prefer it. 3. So why do I need to convert mp3 to WMA?
