Example 1 – The number 200 in the hexadecimal number system will be read as what in decimal?
-: = 2x162 + 0x161 + 0x160
= 512
(200)16 = (512)10
Example 2 – The number 200 in the hexadecimal number system will be read as what in binary?
-: 2 – 0010 0 – 0000 0 – 0000
(200)16 = (001000000000)2
(200)16 = (1000000000)2
Sometimes, the binary number system uses hexadecimal in its place. Since 16 is equal to 24, they have a linear relationship between them. It means that one hex can store four binary digits. It shortens the code for the computer, making it easier to understand. It has undoubtedly more uses:
