0x00000E91

0x00000E91 is a hexadecimal numeric literal commonly used in computing to represent a 32-bit unsigned integer. The value of this literal, when interpreted as a hexadecimal number, is 0x00000E91, which equals decimal 3729. The leading zeros indicate a fixed width, appropriate in contexts such as hardware registers, binary file formats, or network protocols where consistent field sizes are important.

In binary, 0x00000E91 expands to 00000000 00000000 00001110 10010001. This illustrates how hex digits map to four-bit groups, making it convenient to read and compare bit patterns. In memory, 32-bit values may be stored differently depending on endianness: on a little-endian system, the 4-byte sequence would be stored as 91 0E 00 00, whereas big-endian would store it as 00 00 0E 91.

Common uses for such a literal include serving as a simple constant in source code, a small offset or identifier, or a test value in debugging and unit tests. Because 0x00000E91 is not tied to a universal standard code, its meaning is context-specific and derives from the surrounding software, hardware documentation, or data format in which it appears.
