The hexadecimal number system is represented and work using the base of 16. That is content number "0" - "9" and other "A" - "F" it describes 0 to 15. Decimal has only 10 digits 0 to 9. So, Hex is used "A" - "F" for the other 6 characters.
For example, Hex(Base 16) used D for 13 as a decimal(base 10) value and binary 1101.
Each Hexadecimal code has 4 digit binary code.
The hexadecimal number is widely used in computer systems by designers and programmers.
Hexadecimal to Decimal Conversion, For Hex we select base as 16. Multiply Each Digit with a corresponding power of 16 and Sum of them.
Decimal = d X 16n-1 + ... + d X 162 + d X 161 + d X 160
For, 1A in base 16 need to power of 16 with each hex number and Sum of them.
Here, n is 2.
1A = (1 X 16n-1) + (A X 16n-1) = (1 X 161) + (10 X 160) = (1 X 16) + (10 X 1) = 16 + 10 = 26
Let's start Hexadecimal Decode. Here, n is 1.
0.5 = (0 X 16n-1) + (5 X 16n-1) = (0 X 160) + (5 X 16-1) = (0 X 1) + (5 X 0.0625) = 0 + 0.3125 = 0.3125
