kuueteistkümnendnumbrite

Kuueteistkümnendnumbrite, also known as hexadecimal numbers, is a base-16 numeral system. It uses sixteen distinct symbols, typically 0-9 and A-F, to represent numbers. The digits 0 through 9 have their usual values. The letters A through F represent the decimal values 10 through 15, respectively. This system is widely used in computing and digital electronics because it provides a more human-readable representation of binary data.

Each hexadecimal digit can represent four binary digits, also known as a nibble. This is because 2 raised to the power of 4 equals 16. For example, the binary number 1010 is represented by the hexadecimal digit A, and the binary number 1111 is represented by F. This convenient mapping makes it easier to translate between binary and hexadecimal, which is a common task for programmers and system administrators.

The hexadecimal system is particularly useful for representing memory addresses, color codes in web design (e.g., #FF0000 for red), and machine code. Its compactness compared to binary makes it more practical for displaying and manipulating large amounts of data. When reading hexadecimal numbers, the subscript 16 is often used to denote the base, such as 2A5₁₆.
