Hexadecimal Number System
Decimal Number System
1. Write down the decimal equivalent of hexadecimal.
2. Find the position of every digit. We should count the position from the right direction of the number. And the position count starts from 0.
1caf - position of f = 0, a = 1, c = 2, 1 = 3.
5afb - position of b = 0, f = 1, a = 2, 5 = 3.
3. Multiply every digit with 16 to the power of their corresponding position. (16 position)
4. Finally, calculate the sum of all the multiples.
