Binary (base-2) is the fundamental language of computers. Hexadecimal (base-16) is used for memory addresses and color codes. Octal (base-8) is used in some Unix file permissions. Decimal (base-10) is for human-readable numbers. Understanding conversions between these systems is essential for low-level programming and debugging.
Hexadecimal is more compact and human-readable than binary. One hex digit represents four binary digits (bits), making it easier to work with memory addresses, machine code, and bit patterns. For example, the binary number 11011010 becomes DA in hex - much easier to read and remember.
Fractional conversion involves separate processes for the integer and fractional parts. For the fractional part, you multiply by the target base repeatedly. Our calculator handles both integer and fractional number conversions automatically, providing complete results for any decimal input.
Unsigned binary represents only positive numbers. Signed binary (using two's complement) can represent both positive and negative numbers. The leftmost bit indicates the sign (0 for positive, 1 for negative). Our converter handles both representations and explains the conversion process.
