Convert numbers between Binary, Octal, Decimal, and Hexadecimal
Number bases are systems for representing numbers. The most common is Decimal (Base-10), which uses 10 digits (0-9). Computers primarily use Binary (Base-2) (0-1). Hexadecimal (Base-16) (0-9, A-F) and Octal (Base-8) (0-7) are often used in programming as more compact representations of binary data.
