Hexdigiti

Hexdigiti is a term that refers to the hexadecimal digits. These are the ten numerical digits 0 through 9, combined with the six letters A through F. In the hexadecimal number system, these characters represent values from zero to fifteen. Specifically, the digits 0-9 correspond to their usual decimal values, while A represents 10, B represents 11, C represents 12, D represents 13, E represents 14, and F represents 15.

The hexadecimal system is a base-16 positional numeral system. It is widely used in computing and digital electronics because it provides a more human-readable representation of binary-coded values. Since each hexadecimal digit can represent exactly four binary digits (a nibble), it simplifies the conversion between binary and hexadecimal representations. For example, the binary number 1111 is equivalent to the hexadecimal digit F, and 1010 is equivalent to A. This makes it easier for programmers and engineers to work with large binary numbers by grouping them into sets of four bits and representing each group with a single hexadecimal character. This practice is common in memory addressing, color codes in web design (e.g., #FF0000 for red), and data representation in various programming languages and tools.
