sexadecimal number system
Noun: A sexadecimal number system is a positional numeral system that uses a base (radix) of sixteen. It employs sixteen distinct symbols to represent values, typically the digits 0-9 and the letters A-F (or a-f). This system is more commonly known as the hexadecimal number system.
The term is used in mathematics and computing to describe a specific method of numerical representation. It is particularly important in computer science because it provides a more human-friendly way to represent binary-coded values.
- In the sexadecimal number system, the decimal number '10' is represented by the symbol 'A'.
- The color code for white in web design, often written as , is a notation derived from the sexadecimal number system.
- Understanding the sexadecimal number system is essential for low-level programming and digital electronics.
- The sexadecimal number system is fundamental to representing memory addresses, machine code instructions, and encoding data in computing.
- It serves as a convenient shorthand, where one hexadecimal digit directly corresponds to a group of four binary digits (bits).
- Hexadecimal number system: The far more common and preferred synonym for "sexadecimal number system."
- Base-16: A descriptive term for this numeral system.
- Hex: A common abbreviation in computing contexts (e.g., "hex value," "hex editor").
- Hexadecimal system
- Hexadecimal notation
- Base-sixteen system
The term "sexadecimal" is considered archaic and technical. In virtually all modern contexts, especially in computing and engineering, the term hexadecimal is universally used and preferred. "Sexadecimal" may occasionally be found in older academic texts.
