When dealing with different numeral systems in programming, digital circuits, or mathematical calculations, mental conversions are highly prone to errors. This tool accurately converts any integer between binary, octal, decimal, and hexadecimal, instantly outputting the corresponding representations for all bases. Base conversion is essentially processing number systems with different radices (bases); for example, the decimal system uses base 10, while the binary system uses base 2.
Q: Can I use lowercase letters for hexadecimal numbers?
A: Yes. The tool automatically recognizes lowercase letters a-f as valid hexadecimal digits and standardizes the output to uppercase letters A-F to conform to common conventions.
Q: Can this tool convert decimals (fractions) or negative numbers?
A: No. Currently, this tool only supports base conversions for positive integers (non-negative integers). It does not support fractional numbers, negative numbers, or other special characters.
Please ensure that the entered number fully complies with the character set of the selected base (e.g., octal is limited to digits 0-7). All inputs are calculated in real-time within your browser and are never uploaded to our servers, ensuring your privacy. For extremely large values, conversion results may be subject to JavaScript's numeric precision limits.
When debugging code or reading memory addresses, quickly converting between hexadecimal and binary is crucial. A classic example: the hexadecimal value "0xFF" converts to 255 in decimal and "11111111" in binary. Understanding these relationships helps in analyzing bitmasks or color codes. We recommend using this tool to quickly verify binary representations when working with bitwise operations to ensure logical accuracy.
