Understanding Number Systems
Decimal: Base-10 system we use in daily life. Numbers range from 0–9.
Binary: Base-2 system used in computers. Only two digits: 0 and 1.
Octal: Base-8 system using digits from 0–7. Useful in legacy computing.
Hexadecimal: Base-16 system with digits 0–9 and letters A–F. Widely used in programming.
Roman Numerals: Historic system using letters (I, V, X, etc.) for numerical values.
Advanced Topics
For those seeking deeper knowledge:
- Floating-Point Representation: Understanding IEEE-754 formats
- Endianness: Big-endian vs Little-endian data storage
- Signed vs Unsigned: How negative numbers are handled in binary
- Overflow and Rollover: Common issues in 8-bit/16-bit computing
Number Formatting in Programming Languages
- JavaScript: parseInt("1010", 2) converts binary to decimal.
- Python: bin(), hex(), int() functions for easy conversions.
- C/C++: Use format specifiers like %x, %o, or manual bit manipulation.
- Java: Integer.toBinaryString() and similar methods.
