0x1B40

0x1B40 is a hexadecimal literal used in computing to denote the 16-bit unsigned value with the digits 1, B, 4, and 0. In decimal, this value is 6976. In binary, it is 0001 1011 0100 0000. The value can be thought of as two bytes: 0x1B as the high byte and 0x40 as the low byte. Accordingly, in little-endian memory layouts the bytes would be stored as 40 1B, while in big-endian layouts they would be stored as 1B 40.

In programming and data representation, 0x1B40 is commonly used as a constant or data word. It may appear in examples to illustrate hexadecimal notation, bitwise operations, or memory addresses. Depending on the context, it can represent an offset, a configuration parameter, or a portion of a 16-bit data word in embedded or systems programming.

ASCII and binary interpretation: the high byte 0x1B corresponds to the ASCII escape control character, while the low byte 0x40 corresponds to the '@' character. When viewed as a two-byte sequence in a binary payload, 0x1B40 is not a printable ASCII string, but such byte pairs can appear in protocol messages or data streams.

Overall, 0x1B40 exemplifies how hexadecimal notation is used to compactly express 16-bit values in software and hardware contexts, with attention to byte order and interpretation in different systems.
