FAQ
- How does decimal to hexadecimal conversion work?
- Repeatedly divide the decimal number by 16 and record the remainders (0-15, where 10-15 map to A-F). Reading the remainders bottom-to-top gives the hex representation. For example, 255 in hex is FF.
- Where is hexadecimal used?
- Hexadecimal is used extensively in programming: memory addresses, HTML/CSS color codes, byte representations, ASCII/Unicode values, and debugging output. It is a compact way to represent binary data.
- Is hexadecimal case-sensitive?
- No. Hex digits A-F can be written in uppercase or lowercase. Both 0xFF and 0xff represent the same value 255. Different tools and contexts prefer different conventions.
