十六进制转换为二进制 [英] hexadecimal to binary conversion

问题描述

我有个问题：
$ b

1A45（十六进制）GB = _ ____ （二进制）字节

请告诉如何填写答案！

以常规方式进行计算，需要花费很多时间和我无法得到答案......

解决方案

十六进制转换很容易，因为每个十六进制数字是四位长。记住这张表，你就可以很容易地在脑海中进行转换：

  0 0000 
 1 0001 
 2 0010 
 3 0011 
 4 0100 
 5 0101 
 6 0110 
 7 0111 
 8 1000 
 9 1001 
 A 1010 
 B 1011 
 C 1100 
 D 1101 
 E 1110 
 F 1111 
   $ b 
只需将每个十六进制数字替换为其相应的四位数，就可以得到答案的第一部分。
 
 
 <现在对于GB：K表示10个二进制零，M表示20个二进制零，G表示30个二进制零。在您的HEX转换为BIN号码的末尾添加零以获得最终答案。

解决方案
Hex-Bin conversion is easy, because each hex digit is four bit long. Memorize this table, and you'll be able to do conversion in your head very easily:
0 0000
1 0001
2 0010
3 0011
4 0100
5 0101
6 0110
7 0111
8 1000
9 1001
A 1010
B 1011
C 1100
D 1101
E 1110
F 1111
Just replace each hex digit with its corresponding four bits, and you'll get the first part of your answer.

Now for the GB: K means 10 binary zeros, M means 20 binary zeros, G means 30 binary zeros. Add zeros to the end of your HEX-converted-to-BIN number to get your final answer.
