0x1B18

0x1B18 is a hexadecimal literal commonly used in computing to represent an integer value. The prefix 0x indicates hexadecimal notation, so 0x1B18 corresponds to the decimal number 6936. In binary, it is 0001101100011000.

In data encoding and memory, 0x1B18 can denote a 16-bit value. Its byte order depends on endianness: in little-endian systems it appears as 0x18 followed by 0x1B, while in big-endian systems it appears as 0x1B followed by 0x18. This distinction matters when interpreting binary files, network data, or machine instructions.

Common uses include representing registers, bitmasks, or constants in low-level programming, embedded systems, and protocol definitions. In source code, many languages permit writing literals as 0x1B18, for example as an integer constant assigned to a variable. The value can be used in arithmetic, comparisons, or as flags; bitwise operations may isolate specific bits, such as 0x1B18 & 0x00FF to extract the lower byte.

Context determines meaning; without context, 0x1B18 is simply a numeric constant. It could denote a memory address, a port identifier, a protocol value, or a data field in a binary format, depending on how it is used within a system. If interpreted as a Unicode code point, the sequence U+1B18 lies in the Balinese block, highlighting how the same hex pattern can map to different domains when interpreted as code points rather than numeric data.
