What Is the Decimal Number System?
The decimal number system is a base-10 system that uses digits from 0 to 9. It is the most commonly used number system in daily life.
Example:
15 (decimal)
= (1 × 10¹) + (5 × 10⁰)
What Is the Hexadecimal Number System?
The hexadecimal number system is a base-16 system that uses:
- Numbers: 0–9
- Letters: A–F
Where:
- A = 10
- B = 11
- C = 12
- D = 13
- E = 14
- F = 15
Hexadecimal is widely used in programming, memory representation, debugging, and digital systems.
Formula to Convert Decimal to Hexadecimal
Decimal to hexadecimal conversion uses the repeated division by 16 method:
- Divide the decimal number by 16
- Note the remainder
- Divide the quotient again by 16
- Repeat until the quotient becomes 0
- Read the remainders from bottom to top
