Heksadesimaalväärtuse

Heksadesimaalväärtuse is a term that refers to a value represented in the hexadecimal number system. The hexadecimal system, also known as base-16, is a positional numeral system that uses sixteen distinct symbols. These symbols are typically the Arabic numerals 0 through 9, along with the letters A through F to represent the values ten through fifteen.

In the hexadecimal system, each digit's position has a weight that is a power of 16. For example, the hexadecimal number 2AF can be interpreted as (2 * 16^2) + (10 * 16^1) + (15 * 16^0) in decimal, which equals (2 * 256) + (10 * 16) + (15 * 1) = 512 + 160 + 15 = 687.

This system is widely used in computing and digital electronics because it provides a more human-friendly representation of binary-coded values. Since a single hexadecimal digit can represent exactly four binary digits (a nibble), it simplifies the reading and writing of long binary sequences. For instance, the binary number 1111000010101111 can be easily converted to the hexadecimal F0AF.

The use of hexadecimal values is common in various contexts, including memory addressing, color codes in web design (e.g., #FFFFFF for white), and data representation in programming. The abbreviation "hex" is often used when referring to hexadecimal numbers.
