0x1F42
0x1F42 is a hexadecimal integer literal commonly used in computer programming to denote the decimal value 8002. The prefix 0x indicates that the digits that follow are written in base 16. Hex literals are widely used for low‑level programming tasks such as memory addressing, bitwise operations, and defining constants that correspond to binary data or hardware registers. In many languages, the same numeric value can be formatted differently (for example, as 8002 in decimal or 0x1F42 in hex) and may be subject to the language’s integer size and signedness rules.
In Unicode terms, the hexadecimal value 1F42 corresponds to a code point written as U+1F42. This code
