0x1C0

0x1C0 is a hexadecimal literal commonly used in computing to denote the integer value represented by the hex digits 1, C, and 0. In decimal, 0x1C0 equals 448. In binary, it is 0001 1100 0000, and in octal it is 700.

Hex literals like 0x1C0 are a standard way to specify values in source code, memory addresses, and binary masks. They are often preferred over decimal notation because each hex digit corresponds to four binary bits, making bit-level patterns easier to read and compare. The value 0x1C0, for example, consists of the bits at positions 8, 7, and 6 being set (256 + 128 + 64).

Common uses include initializing constants in programming languages, representing memory addresses or offsets, and serving as bit masks to test, set, or clear specific bits in hardware registers or data structures. As a bit mask, 0x1C0 specifically selects the upper three bits of a given 9-bit window (bits 6 through 8 in zero-based indexing), which can be relevant in low-level programming or hardware control contexts.

Context is essential for interpretation. The meaning of 0x1C0 depends on the architecture, data width, and surrounding code or documentation. It may denote an address offset, a register value, a constant used in calculations, or a component of a protocol field.

There is no single canonical meaning for 0x1C0 beyond its numeric value; its role is defined by the system in which it appears.
