A Number System Converter is a tool or algorithm that allows you to convert a number from one numeral system (or base) to another. Number systems are ways of representing numbers using different sets of symbols or digits. Commonly used number systems include:
Common Number Systems:
-
Binary (Base 2):
- Uses digits 0 and 1.
- Example: 101021010_2 1010 2 (binary) = 101010_{10} 10 10 (decimal)
-
Decimal (Base 10):
- The standard number system most people use in everyday life, using digits 0–9.
- Example: 101010_{10} 10 10 (decimal) = 101021010_2 1010 2 (binary)
-
Octal (Base 8):
- Uses digits 0–7.
- Example: 12812_8 12 8 (octal) = 101010_{10} 10 10 (decimal)
-
Hexadecimal (Base 16):
- Uses digits 0–9 and letters A–F (where A=10, B=11, C=12, etc.).
- Example: A16A_{16} A 16 (hexadecimal) = 101010_{10} 10 10 (decimal)
-
Base 36:
- Uses digits 0–9 and letters A–Z (with A=10, B=11, ..., Z=35).
- Example: 193619_{36} 19 36 (base 36) = 451045_{10} 45 10 (decimal)
Purpose of a Number System Converter:
- Converting between systems: A converter allows you to convert numbers from one base (like binary) to another (like decimal), making it useful for people working in fields like computer science, cryptography, electronics, and mathematics.
- Learning and understanding: It helps students and professionals learn about different bases and how numbers can be represented in various ways.
- Software development: Developers often need to convert between bases when working with data in different formats or performing operations in different numeric bases.
Common Conversions:
- Binary to Decimal
- Decimal to Binary
- Binary to Octal
- Decimal to Octal
- Hexadecimal to Decimal
- Decimal to Hexadecimal
- Base 36 to Decimal
- Decimal to Base 36
