Method: the decimal part is the same as the integer part, just add the decimal point to the decimal part
93.14 is represented by 8421BCD Code: 1001 0011.0001 0100
93bcd Code: 1001 0011
9 BCD code: 1001
3 BCD code: 0011
0.14 BCD code: 0.0001 0100
1 BCD code: 0001
4 BCD code: 0100
extended data:
1 Conversion between BCD code and decimal number; 0111,5-> 0101,4-> So the result of 8421BCD is: (0111 0101.0100) BCD; If BCD code 1000 0101.0101 is converted to decimal number: 1000 - & gt; 8,0101-> 5,0101-> So the result is: (85.5) d
note: the number represented by the same 8-bit binary code is not the same when it is considered to be a binary number and a binary coded decimal number
for example: 00011000, when it is regarded as a binary number, its value is 24; But as a 2-bit BCD code, its value is 18
another example is 00011100. If it is regarded as a binary number, its value is 28, but it can not be regarded as BCD code, because in 8421BCD code, it is an illegal code
2, BCD code format
in computer BCD code, there are two formats often used, that is, separate BCD code, combined BCD code
the so-called separated BCD code is to use the lower four bits of a byte to represent one bit of a decimal number. For example, the storage format of number 82 is:
_ 1 0 0 0 _ _ _ _ 0 0 1 0 where_ Represents an unrelated value
combining BCD code is to store two decimal numbers in one byte. The storage format of example 82 is 1000 100

Xeon (Xeon), is Intel's server oriented processor, which is mainly used in enterprise servers and workstations. Intel processor layout is as follows: server Xeon, desktop and notebook are core I series + Pentium + Celeron. But in recent years, Xeon Series CPU has graally entered the "ordinary people" host, and some models are also very popular. For the moment, regardless of the mainstream Xeon E3 series, even the most powerful CPUs with 1366 and 775 interfaces in previous years are extremely popular. But these hot old u have a bad name - "foreign garbage"
generally speaking, these Xeon series CPUs are mainly disassembled from foreign servers or exiled from OEM channels. Of course, they are all obsolete procts, so we call them "foreign garbage". The merchants buy directly from developed countries such as Europe, America and Japan, transport them back to China for sale (with containers as the unit), and then classify the "foreign garbage" and sell them to retail investors
generally, incoming goods are not classified. When you are lucky, CPU, memory, motherboard, hard disk and chassis can be sold at a good price; The truth is like a gambler. A few years ago, such as 1366, 775 interface of the most powerful CPU is classified in this way, and finally through the online trading platform flow to the hands of consumers. These "foreign garbage" CPUs can be roughly classified by interface, including 771 and 775 interfaces: Xeon e5450; There are 1156, 1366 interfaces: Xeon l5639, X5650, etc.
