Engineering Notes
Hex to Decimal
Hex is base-16 (0-F), decimal is base-10. 0xFF = 255, 0x100 = 256. Use this converter to quickly switch between hex, decimal, and binary representations.
Little-Endian Example
0x12345678 in little-endian is stored as bytes: 78 56 34 12. The least significant byte (0x78) comes first in memory.
