0xDAFA
0xDAFA is a hexadecimal representation of a number. In computing, hexadecimal (often shortened to hex) is a base-16 numeral system. It uses sixteen distinct symbols, most commonly the digits 0-9 and the letters A-F. Each symbol represents a value from 0 to 15. The prefix "0x" is a common convention used in many programming languages to denote that a number is represented in hexadecimal.
In the case of 0xDAFA, the digits are D, A, F, and A. The letter D represents
A (10) * 16^2 = 10 * 256 = 2560
D (13) * 16^3 = 13 * 4096 = 53248
Summing these values: 10 + 240 + 2560 + 53248 = 56058. Therefore, 0xDAFA is equivalent to the decimal number
