- A positional system that represents numbers using a base of 16. Unlike the common way of representing numbers with 10 symbols, hexadecimal uses 16 distinct symbols, most often the symbols “0”–“9” to represent values 0–9, and “A”–“F” (or alternatively “a”–“f”) to represent values 10–15. ← Wikipedia
