0x180

0x180 is a hexadecimal numeric literal used in many programming languages. The prefix “0x” indicates that the following digits are in base­16. In base‑10, 0x180 equals 384. Its binary expansion is 1 1000 0000, which shows that the bit at position eight (counting from zero) is set while the higher bits remain zero. The value can therefore be written as 2⁸ + 2⁹, or 256 + 128.

In computing, hexadecimal numbers are popular when dealing with addresses, error codes, or bit‑mask values. For example, the address 0x180 is often used in microcontroller memory maps as the location of a specific peripheral register, such as a timer or UART control register. In the Intel 80386 architecture, the invalid opcode exception handler is typically located at address 0x180. Because this address aligns on a 256‑byte boundary, it is easy to reference in assembly programs that use segment registers.

Syntax for 0x180 is almost identical across languages. In C, C++, and Java, the literal can be written as 0x180 and has type int. In Python, the same syntax creates an integer object. Many debuggers and disassemblers display addresses in hexadecimal, so the symbol 0x180 appears frequently in core dumps and tracebacks.

Overall, 0x180 is an example of a hexadecimal constant whose decimal counterpart is 384, with straightforward binary representation and several common uses in low‑level software and hardware documentation.
