0x631

0x631 is a hexadecimal number, which is a base-16 numeral system used in computing and digital electronics. In decimal notation, 0x631 is equivalent to 1585. The prefix "0x" is commonly used to denote a hexadecimal number in programming and digital contexts. Hexadecimal is widely used because it provides a more human-friendly representation of binary-coded values, which are fundamental to digital computing.

Hexadecimal numbers are composed of 16 distinct symbols: 0-9 to represent values zero to nine, and A-F (or a-f) to represent values ten to fifteen. Each digit in a hexadecimal number represents a power of 16. For example, in the number 0x631, the digit '6' represents 6 times 16^2, '3' represents 3 times 16^1, and '1' represents 1 times 16^0.

The conversion from hexadecimal to decimal involves multiplying each digit by the corresponding power of 16 and summing the results. This process is straightforward and is often used in low-level programming, hardware design, and data representation. Hexadecimal notation is also used in color codes in web design, memory addresses in computer systems, and various other fields where binary data needs to be represented in a more readable format.
