### Hex to Decimal and Decimal to Hex

Hex System
Hex or hexadecimal is a number system with a base 16. This number system is especially interesting because in the decimal number system we have only 10 digits to present the numbers. As the hex system has 16 digits, the first 6 letters of the English alphabet are used to represent extra 6 digits. So, hex digits are 0,1,2,3,4,5,6,7,8 and 9 A, B, C, D, E, F.

Decimal System
Decimal number system is also known as the Base 10 numbering system because it is based on 10 ranging symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. In the decimal system, every digit holds its own position along with the decimal point. I.e. the number 326.34 has 4 in the Hundredths position, 3 in the Tenths position, 6 in the Unit position, 2 in the Tens position, and 3 in the Hundreds position.

Decimal number system is also one of the ancient numeral system, whose roots are in Hindu-Arabic numeral system.
