Understanding Hexadecimal
What is Hexadecimal?
Hexadecimal (hex) is a base-16 number system that uses 16 distinct symbols: 0-9 and A-F (where A=10, B=11, C=12, D=13, E=14, F=15).
Why Use Hexadecimal?
- Compact representation: One hex digit represents 4 binary digits
- Memory addresses: Computer memory addresses are often displayed in hex
- Color codes: Web colors are represented as 6-digit hex codes (RRGGBB)
- Programming: Hex is commonly used in low-level programming
Hex to Decimal Conversion
Each position in a hex number represents a power of 16:
A1B2āā = AĆ16³ + 1Ć16² + BĆ16¹ + 2Ć16ā° = 10Ć4096 + 1Ć256 + 11Ć16 + 2Ć1 = 41394āā
Example Calculations
Hexadecimal Addition
A1 + B2 = 153
In decimal: 161 + 178 = 339
Bitwise AND
FF & AA = AA
In binary: 11111111 & 10101010 = 10101010
Color Code Example
FF5733 = Red: FF (255), Green: 57 (87), Blue: 33 (51)
This creates an orange-red color
Frequently Asked Questions
What does the '0x' prefix mean?
The '0x' prefix is a common notation in programming to indicate that a number is in hexadecimal format. For example, 0xFF represents the hex number FF.
How do I convert decimal to hexadecimal?
Divide the decimal number by 16 repeatedly and collect the remainders. Convert remainders 10-15 to A-F. For example, 255 Ć· 16 = 15 remainder 15 (F), 15 Ć· 16 = 0 remainder 15 (F). Result: FF.
Why is hexadecimal used for colors?
Hex color codes use 6 digits (RRGGBB) where each pair represents the intensity of red, green, and blue from 00 (0) to FF (255). This provides 16.7 million possible colors.
